A simulated map of gravitational-wave emitters in our galaxy reveals the promise that lays behind 'multi-messenger astronomy.'
are able to detect gravitational waves of frequencies between 5 and 20,000 Hertz. Ultracompact binaries in our galaxy, as they spiral around each other and eventually merge, have frequencies in the range of milliHertz.'s Laser Interferometer Space Antenna is at the forefront, with launch projected to be in the 2030s, while Chinese scientists also have two mission concepts, named TianQin and Taiji, respectively.
Chirenti is part of a team, led by Kaitlyn Szekerczes of the Gravitational Astrophysics Laboratory at NASA Goddard, who have now simulated the intensity and frequency of gravitational waves emitted by ultracompact binaries in the Milky Way. The resulting image shows how observatories such as LISA will be able to study the Milky Way in gravitational waves just like astronomers study it in X-rays,

Model suggests Milky Way warp and flare due to tilt of dark haloA trio of astrophysicists with Harvard and Smithsonian's Center for Astrophysics has found via computer modeling that the likely reason for the warp and flare of the Milky Way galaxy is a tilt of the dark halo. In their paper published in the journal Nature Astronomy, Jiwon Jesse Han, Charlie Conroy and Lars Hernquist describe their theories regarding the shape of the Milky Way galaxy and what their model showed.
