ABSTRACTThe Galactic center is a superb laboratory of modern astrophysics where astronomers can study at unprecedented spatial resolution and across the entire electromagnetic spectrum physical processes that may also happen at the cores of other galaxies. Following a brief review of the phenomena observed in the central few hundred parsecs, we discuss

A brief review of galactic center observations, from the radio to gamma rays, is presented. There is evidence for black holes in the central region of the Galaxy at all wavelengths, but the observations are not unambiguous and a single massive object at the dynamic center may not explain the data at all wavelengths. Requirements for future observations

The center of our Galaxy provides a uniquely accessible laboratory. It is a rich environment of extreme density, velocity and tidal fields of stars. It is the closest example of a galactic nucleus and could give the opportunity to understand the role that massive black-holes play in the formation and evolution of galaxies. It could be used to test the

The Galactic Center large program
AIP Conference Proceedings, 2008We report a multi‐epoch and multi‐wavelength observation campaign of the Galactic Center. Some results are first presented before stressing more specifically the 8.6 micron observations obtained with VLT/VISIR used in burst mode during three nights in July 2007.

The Galactic Center in the IR — VLT Infrared Observations of the Galactic Center [PDF]
, 1997 The ISAAC system at the ESO VLT (Very Large Telescope) UT1 telescope has been used to image the central stellar cluster of the Milky Way in the mid-infrared L- and M-band (3.3 µm and 4.6 µm), with a field of view of 72.6″×72.6″.These obsevations were part of a program to monitor the MIR flux density at the position of Sgr A* and were carried out ...

The Galactic Center with Roman
2023We advocate for a Galactic center (GC) field to be added to the Galactic Bulge Time Domain Survey (GBTDS). The new field would yield high-cadence photometric and astrometric measurements of an unprecedented ${\sim}$3.3 million stars toward the GC. This would enable a wide range of science cases, such as finding star-compact object binaries that may ...

Deciphering the morphology and kinematics of the galactic center constitutes one of the enduring programs of the study of galactic structure. This is especially true for radio astronomy, which was the first of the astronomical sciences to penetrate the mysteries of the galactic center, but radio-frequency observations alone cannot provide more than a ...
