Anomalous gamma-ray excess emissions
An anomalous gamma-ray excess emission has been found in the Fermi Large Area Telescope data covering the centre of the Galaxy. Several theories have been proposed for this... -
Bulge RR Lyrae VVVDR4 photometry
This study's objective was to exploit infrared VVV (VISTA Variables in the Via Lactea) photometry for high latitude RRab stars to establish an accurate Galactic Centre distance.... -
Short-period binaries in the inner VVV bulge
Most of our knowledge of the structure of the Milky Way has come from the study of variable stars. Among these variables, mimicking the periodic variation of pulsating stars,... -
2D kinematics of massive stars
The presence of massive stars (MSs) in the region close to the Galactic Centre (GC) poses several questions about their origin. The harsh environment of the GC favours specific... -
Pressure components in the central HII regions
Supernovae (SNe) dominate the energy and momentum budget of stellar feedback, but the efficiency with which they couple to the interstellar medium (ISM) depends strongly on how... -
Metallicity distribution in GC
We present stellar metallicity measurements of more than 600 late-type stars in the central 10pc of the Galactic Centre. Together with our previously published KMOS data, this... -
AGN luminosity fraction in merging galaxies
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... -
Quantifying maximum discs in galaxies
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... -
1.87 and 2.07um observations of 3 GC clusters
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... -
Microlensing event rate in the GC. I. UKIRT obs.
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... -
High-velocity dispersion compact clouds in the CMZ
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... -
Accurate OH maser positions. II. The GC.
We present high spatial resolution observations of ground-state OH masers achieved using the Australia Telescope Compact Array (ATCA). These observations were conducted toward... -
Ultradeep catalog of X-ray point sources in the GC
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... -
SCUBA-2 Galactic Center compact source catalog
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... -
Massive YSOs in the GC. II. IRTF spectra
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... -
Galactic center compact radio sources from JVLA obs.
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... -
HCN, HNC, H13CN & HC3N of Galactic Center map. II.
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... -
Radio continuum param. of Galactic HII regions
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... -
Abundances and ages of stars in the Milky Way bulge
The age and chemical characteristics of the Galactic bulge link to the formation and evolutionary history of the Galaxy. Data-driven methods and large surveys enable stellar... -
Gas structure comparison; NGC 253 and Milky Way
We compare molecular gas properties in the starbursting center of NGC253 and the Milky Way Galactic center (GC) on scales of ~1-100pc using dendrograms and resolution-, area-,...
