We report the detection of variable stars within a 11.5arcminx11.5arcmin region near the Galactic Centre that includes the Arches and Quintuplet clusters, as revealed by the...

Galaxy mergers are key events in galaxy evolution, often causing massive starbursts and fueling active galactic nuclei (AGNs). In these highly dynamic systems, it is not yet...

Maximum disc decompositions of rotation curves place a dynamical upper limit to the mass attributable to stars in galaxies. The precise definition of this term, however, can be...

In order to investigate populations of massive stars in massive star clusters, we have constructed a near-infrared image set: narrow bands of 1.87 and 2.07{mu}m and the Ks...

To overcome the high optical extinction, near-infrared (NIR) observations are needed for probing the microlensing events toward the Galactic center. The 2015-2019 UKIRT...

This study developed an automated identification procedure for compact clouds with broad velocity widths in the spectral-line data cubes of highly crowded regions. The procedure...

The Galactic Plane Infrared Polarization Survey (GPIPS) seeks to characterize the magnetic field in the dusty Galactic disk using near-infrared stellar polarimetry. All GPIPS...

We present new observations of the C-band continuum emission and masers to assess high-mass (>8M_{sun}) star formation at early evolutionary phases in the inner 200pc of the...

We present high spatial resolution observations of ground-state OH masers achieved using the Australia Telescope Compact Array (ATCA). These observations were conducted toward...

We present an updated catalog of X-ray point sources in the inner 500" (~20pc) of the Galactic center (GC), where the nuclear star cluster (NSC) stands, based on a total of...

We present new JCMT SCUBA-2 observations of the Galactic Center region from 355{deg}<l<5{deg} and b<+/-1{deg}, covering 10x2 square degrees along the Galactic Plane to...

We present the first estimate of the intrinsic binary fraction of young stars across the central ~0.4pc surrounding the supermassive black hole (SMBH) at the Milky Way Galactic...

We measure the 3D kinematic structures of the young stars within the central 0.5pc of our Galactic Center using the 10m telescopes of the W. M. Keck Observatory over a time span...

We present the results of the first systematic search for spectroscopic binaries within the central 2x3arcsec^2^ around the supermassive black hole at the center of the Milky...

We report the first star formation history study of the Milky Ways nuclear star cluster (NSC), which includes observational constraints from a large sample of stellar...

We present a large ~30"x30" spectroscopic survey of the Galactic Center using the SINFONI IFU at the VLT. Combining observations of the last two decades we compile spectra of...

To study the demographics of interstellar ices in the Central Molecular Zone (CMZ) of the Milky Way, we obtain near-infrared spectra of 109 red point sources using NASA...

Using Jansky Very Large Array data obtained from high-resolution observations at 5.5GHz at multiple epochs in 2014 and 2019, we have detected a population of radio variables and...

We report a statistical analysis exploring the origin of the overall low star formation efficiency (SFE) of the Galactic central molecular zone (CMZ) and the SFE diversity among...

Sgr E is a massive star formation complex found toward the Galactic center that consists of numerous discrete, compact HII regions. It is located at the intersection between the...
