Multimessenger Astronomy
Overview
This gallery brings together animations, visualizations, videos and still images relating to the growing field of “multimessenger” astronomy.
In the past century, humans have mastered how to detect light beyond what our eyes can see — unveiling secrets held in other parts of the electromagnetic spectrum. More recently, we have developed detectors for other signals from the universe — particles ejected from black holes and other high-energy sources and even wiggles of space-time in the form of gravitational waves. This new capability of combining information from all of these different messengers to more completely understand a source is called multimessenger astronomy.
The four messengers astronomers study are light in all its forms, cosmic rays, neutrinos, and gravitational waves.
When an astronomical source varies slowly, astronomers can combine information from different messengers received at different times — sometimes even years apart — and still get a good picture of it. But many source types change rapidly with time. For them, it’s critical that observations occur simultaneously or within a short time span so that astronomers capture the properties of different messengers before the source changes. Astronomers call this “time domain” astronomy. Multimessenger time domain astronomy is a powerful new tool for exploring the cosmos.

Fermi Explores Supernova Remnants
Go to this pageFermi's Large Area Telescope (LAT) resolved gamma rays with energies a billion times greater than that of visible light from supernova remnants of different ages and in different environments. W51C, W44 and IC 443 are middle-aged remnants between 4,000 and 30,000 years old. The youngest remnant, Cassiopeia A, is only 330 years old and appears to the LAT as a point source. The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles — cosmic rays. The emissions are likely the result of accelerated protons interacting with nearby gas clouds, but other possibilities have not been eliminated. Astrophysicists believe that supernova remnants are the galaxy's best candidate sites for cosmic-ray acceleration. These observations provide further validation to the notion that supernova remnants act as enormous accelerators for cosmic particles. ||

Fermi Proves Supernova Remnants Produce Cosmic Rays
Go to this pageA new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward meeting one of Fermi's primary mission goals.Cosmic rays are subatomic particles that move through space at nearly the speed of light. About 90 percent of them are protons, with the remainder consisting of electrons and atomic nuclei. In their journey across the galaxy, the electrically charged particles become deflected by magnetic fields. This scrambles their paths and makes it impossible to trace their origins directly.Through a variety of mechanisms, these speedy particles can lead to the emission of gamma rays, the most powerful form of light and a signal that travels to us directly from its sources.Two supernova remnants, known as IC 443 and W44, are expanding into cold, dense clouds of interstellar gas. This material emits gamma rays when struck by high-speed particles escaping the remnants.Scientists have been unable to ascertain which particle is responsible for this emission because cosmic-ray protons and electrons give rise to gamma rays with similar energies. Now, after analyzing four years of data, Fermi scientists see a gamma-ray feature from both remnants that, like a fingerprint, proves the culprits are protons.When cosmic-ray protons smash into normal protons, they produce a short-lived particle called a neutral pion. The pion quickly decays into a pair of gamma rays. This emission falls within a specific band of energies associated with the rest mass of the neutral pion, and it declines steeply toward lower energies. Detecting this low-end cutoff is clear proof that the gamma rays arise from decaying pions formed by protons accelerated within the supernova remnants.In 1949, the Fermi telescope's namesake, physicist Enrico Fermi, suggested that the highest-energy cosmic rays were accelerated in the magnetic fields of interstellar gas clouds. In the decades that followed, astronomers showed that supernova remnants were the galaxy's best candidate sites for this process.?A charged particle trapped in a supernova remnant's magnetic field moves randomly throughout it and occasionally crosses through the explosion's leading shock wave. Each round trip through the shock ramps up the particle's speed by about 1 percent. After many crossings, the particle obtains enough energy to break free and escapes into the galaxy as a newborn cosmic ray. The Fermi discovery builds on a strong hint of neutral pion decay in W44 observed by the Italian Space Agency's AGILE gamma-ray observatory and published in late 2011.Watch this video on YouTube. ||

How Cosmic-ray Protons Make Gamma rays
Go to this pageIn the simplest and most common interaction, a cosmic-ray proton strikes another proton. The protons survive the collision, but their interaction creates an unstable particle — a pion — with only 14 percent the mass of a proton. In 10 millionths of a billionth of a second, the pion decays into a pair of gamma-ray photons. More complex scenarios occur when cosmic-ray protons strike nuclei containing greater numbers of particles. ||

Doomed Neutron Stars Create Blast of Light and Gravitational Waves
Go to this pageThis animation captures phenomena observed over the course of nine days following the neutron star merger known as GW170817, detected on Aug. 17, 2017. They include gravitational waves (pale arcs), a near-light-speed jet that produced gamma rays (magenta), expanding debris from a kilonova that produced ultraviolet (violet), optical and infrared (blue-white to red) emission, and, once the jet directed toward us expanded into our view from Earth, X-rays (blue).

NASA's Fermi Preps to Narrow Down Gravitational Wave Sources
Go to this pageFermi's GBM saw a fading X-ray flash at nearly the same moment LIGO detected gravitational waves from a black hole merger in 2015. This movie shows how scientists can narrow down the location of the LIGO source on the assumption that the burst is connected to it. In this case, the LIGO search area is reduced by two-thirds. Greater improvements are possible in future detections.Credit: NASA's Goddard Space Flight Center Watch this video on the NASAgovVideo YouTube channel. || LIGO_GBM_Common_only_Earth.png (1920x1080) [4.2 MB] || LIGO_GBM_Common_only_Earth_print.jpg (1024x576) [168.3 KB] || LIGO_GBM_Common_only_Earth_searchweb.png (320x180) [97.0 KB] || LIGO_GBM_Common_only_Earth_web.png (320x180) [97.0 KB] || LIGO_GBM_Common_only_Earth_thm.png (80x40) [6.6 KB] || Fermi_LIGO_GBM_localizations_H264_YouTube_1080p.mp4 (1920x1080) [82.8 MB] || Fermi_LIGO_GBM_localizations_H264_720p.mp4 (1280x720) [35.4 MB] || Fermi_LIGO_GBM_localizations_H264_720p.webm (1280x720) [2.3 MB] || 12216_Fermi_LIGO_Localization_4K.mov (4096x2304) [90.6 MB] || Fermi_LIGO_GBM_localizations_ProRes_1920x1080_30.mov (1920x1080) [431.3 MB] || 12216_Fermi_LIGO_Localization_ProRes_7282x4096_30.mov (7282x4096) [6.0 GB] || 12216_Fermi_LIGO_Localization_4K.m4v (3840x2160) [140.3 MB] ||

Simulations Uncover 'Flashy' Secrets of Merging Black Holes
Go to this pageAccording to Einstein, whenever massive objects interact, they produce gravitational waves — distortions in the very fabric of space and time — that ripple outward across the universe at the speed of light. While astronomers have found indirect evidence of these disturbances, the waves have so far eluded direct detection. Ground-based observatories designed to find them are on the verge of achieving greater sensitivities, and many scientists think that this discovery is just a few years away. Catching gravitational waves from some of the strongest sources — colliding black holes with millions of times the sun's mass — will take a little longer. These waves undulate so slowly that they won't be detectable by ground-based facilities. Instead, scientists will need much larger space-based instruments, such as the proposed Laser Interferometer Space Antenna, which was endorsed as a high-priority future project by the astronomical community. A team that includes astrophysicists at NASA's Goddard Space Flight Center in Greenbelt, Md., is looking forward to that day by using computational models to explore the mergers of supersized black holes. Their most recent work investigates what kind of "flash" might be seen by telescopes when astronomers ultimately find gravitational signals from such an event. To explore the problem, a team led by Bruno Giacomazzo at the University of Colorado, Boulder, and including Baker developed computer simulations that for the first time show what happens in the magnetized gas (also called a plasma) in the last stages of a black hole merger. In the turbulent environment near the merging black holes, the magnetic field intensifies as it becomes twisted and compressed. The team suggests that running the simulation for additional orbits would result in even greater amplification. The most interesting outcome of the magnetic simulation is the development of a funnel-like structure — a cleared-out zone that extends up out of the accretion disk near the merged black hole. The most important aspect of the study is the brightness of the merger's flash. The team finds that the magnetic model produces beamed emission that is some 10,000 times brighter than those seen in previous studies, which took the simplifying step of ignoring plasma effects in the merging disks. ||
