1482 Gaussian clumps in the Central Molecular Zone
We carry out a systematic study of the density structure of gas in the Central Molecular Zone (CMZ) in the Galactic center by extracting clumps from the APEX Telescope Large... -
VVV survey microlensing events; -3.7<b{<}-3.9{deg}
We search for microlensing events in fields along the Galactic minor axis, ranging from the Galactic center to -3.7{deg}<b<3.9{deg} using the VISTA Variables in the Via... -
Keck/NIRC2 obs. of the Galactic Center
Precision measurements of the stars in short-period orbits around the supermassive black hole at the Galactic Center are now being used to constrain general relativistic... -
Molecular cloud cores in the GC 50km/s cloud
The Galactic center 50km/s molecular cloud (50MC) is the most remarkable molecular cloud in the Sagittarius A region. This cloud is a candidate for the massive star formation... -
Sgr A* 1.3mm VLBI observations with the EHT in 2013
We report results from very long baseline interferometric (VLBI) observations of the supermassive black hole in the Galactic center, Sgr A, at 1.3mm (230GHz). The observations... -
Spitzer/IRS observations of the Galactic Center
It has long been shown that the extreme ultraviolet spectrum of the ionizing stars of HII regions can be estimated by comparing the observed line emission to detailed models. In... -
Compact clouds in a sensitive GBT HI survey
We present the results of a new sensitive survey of neutral hydrogen above and below the Galactic Center with the Green Bank Telescope. The observations extend up to Galactic... -
16yrs of radial velocity measurements of S0-2
The star S0-2, which orbits the supermassive black hole (SMBH) in our Galaxy with a period of 16 years, provides the strongest constraint on both the mass of the SMBH and the... -
NuSTAR hard X-ray survey of the Galactic Center. II.
We present the first survey results of hard X-ray point sources in the Galactic Center (GC) region by NuSTAR. We have discovered 70 hard (3-79 keV) X-ray point sources in a 0.6... -
First Fermi-LAT Inner Galaxy point source catalog
The Fermi Large Area Telescope (LAT) has provided the most detailed view to date of the emission toward the Galactic center (GC) in high-energy {gamma}-rays. This paper... -
Period variations of 32 contact binaries
We present detailed analyses of updated eclipse timing diagrams for 32 contact binary merger candidates in the Galactic bulge. The photometric data was obtained from 2016 to... -
The internal Faraday screen of Sagittarius A*
We report on 85-101 GHz light curves of the Galactic Center supermassive black hole, Sagittarius A (Sgr A), observed in April 2017 with the Atacama Large... -
Galactic center maser-bearing Miras
This sample of 370 Mira variables that are likely near the Galactic center (GC) has been selected from the OGLE and BAaDE surveys based on their sky coordinates, OGLE... -
GC and inner disc XMM-Newton observations
The diffuse Fe XXV (6.7keV) line emission observed in the Galactic ridge is widely accepted to be produced by a superposition of a large number of unresolved X-ray point... -
Milky Way's Nuclear Stellar Disc pm catalog
We present the results of a large-scale proper motion study of the central ~36'x16' of the Milky Way, based on our high angular resolution GALACTICNUCLEUS survey (epoch 2015)... -
GALACTICNUCLEUS IV. JHKs imaging survey
The extreme extinction (A_V_~30mag) and its variation on arc-second scales towards the Galactic centre hamper the study of its stars. Their analysis is restricted to the near... -
Arches cluster JVLA 6 and 10GHz images
We present high angular resolution radio observations of the Arches cluster in the Galactic centre, one of the most massive young clusters in the Milky Way. The data were... -
CS isotopes towards Galactic centre clouds
Measuring isotopic ratios is a sensitive technique to obtain information on stellar nucleosynthesis and chemical evolution. We present measurements of the carbon and sulphur... -
Gal. Center MAGIC diffuse gamma-ray emission
In the presence of a sufficient amount of target material, gamma rays can be used as a tracer in the search for sources of Galactic cosmic rays (CRs). Here we present deep... -
Milky Way nuclear star cluster HKs photometry
The environment of Sagittarius A (Sgr A), the central black hole of the Milky Way, is the only place in the Universe where we can currently study the interaction between a...
