Massive Stars Play a Crucial Role in Shaping Their Surroundings: How Do the Simulation Models Stack Up?
Less than one percent of stars in a galaxy are formed with masses exceeding ten solar masses. Despite their rarity, massive stars are believed to…
Supermassive Black Holes: The Ultimate Snitches Giving Away Galactic Center Secrets
The Universe contains different “flavors” of black holes. While “stellar” mass black holes are 10-50 times the mass of our Sun, supermassive black holes are…
Gravitational Wave Scientists Pioneer New Laser Mode Sensor With Unprecedented Precision
Lasers support certain structures of light known as “eigenmodes.” An international collaboration of experts in gravitational waves, metasurfaces, and photonics has pioneered a new method…
Why Double Neutron Star Systems – Hulse-Taylor Binary Pulsars – Are So Rare
The High Time Resolution Universe Pulsar Survey Double neutron star (DNS) systems in tight orbits are fantastic laboratories to test Einstein’s general theory of relativity….
Continuous Gravitational Waves in the Lab
Gravitational-waves are ripples in space-time created by distant astronomical objects and detected by large complex detectors (like LIGO, Virgo, and KAGRA). Finding gravitational-wave signals in…
Misbehaving Pulsars: Unexpected Changes in the Most Predictable of Stars
Pulsars, a class of neutron stars, are extremely predictable stars. They are formed from the hearts of massive stars that have since collapsed in on…
Searching for Elusive Continuous Gravitational Waves From the Densest Objects in the Universe
A new international study, led by an Australian researcher from the ARC Centre of Excellence for Gravitational Wave Discovery, searched for elusive continuous gravitational waves…
A New Approach To Rapidly Localize Gravitational Waves To Coordinate Prompt Follow-Up Observations
Multimessenger astronomy is an emerging field that aims to study astronomical objects using different ‘messengers’ or sources, like electromagnetic radiation (light), neutrinos, and gravitational waves….
Explaining “Invisible” Black Holes: How Stellar Winds Can Create Disks Around Black Holes
The first evidence of the existence of black holes was found in the 1960s, when strong X-rays were detected from a system called Cygnus X-1….
Discovering Dark Matter: New Clue From Mysterious Clouds Circling Spinning Black Holes
Gravitational waves are cosmic ripples in the fabric of space and time that emanate from catastrophic events in space, like collisions of black holes and…
Weak Supernova Explosions From Isolated Stars
Many of the heaviest stars in the Universe will end their lives in a bright explosion, known as a supernova, which briefly outshines the rest…
