We analyze the gas and dust emission in the immediate vicinity of the supermassive black hole Sgr A* at the Galactic center (GC) with the ESO Very Large Telescope (Paranal/Chile) instruments SINFONI and VISIR. The SINFONI H+K data cubes show several emission lines with related line map counterparts. From these lines, the Brγ emission is the most prominent one and appears to be shaped as a bar extending along the north–south direction. With VISIR, we find a dusty counterpart to this filamentary… 

Evidence for a jet and outflow from Sgr A*: a continuum and spectral line study

We study the environment of Sgr A* using spectral and continuum observations with the ALMA and VLA. Our analysis of sub-arcsecond H30alpha, H39alpha, H52alpha and H56alpha line emission towards Sgr

Constraining the accretion flow density profile near Sgr A* using the L′-band emission of the S2 star

Context. The density of the ambient medium around a supermassive black hole (SMBH) and the way it varies with distance plays an important role in our understanding of the inflow-outflow mechanisms in

The origin of hotspots around Sgr A*: orbital or pattern motion?

The Gravity Collaboration detected a near-infrared hotspot moving around Sgr A* during the 2018 July 22 flare. They fitted the partial loop the hotspot made on the sky with a circular Keplerian orbit

Observation of S4716—a Star with a 4 yr Orbit around Sgr A*

The ongoing monitoring of the Galactic center and Sgr A*, the central supermassive black hole, produces surprising and unexpected findings. This goes hand in hand with the technical evolution of

The Apparent Tail of the Galactic Center Object G2/DSO

Observations of the near-infrared excess object G2/DSO increased attention toward the Galactic center and its vicinity. The predicted flaring event in 2014 and the outcome of the intense monitoring

Nonthermal Emission from Fall-back Clouds in the Broad-line Region of Active Galactic Nuclei

The spectra of active galactic nuclei exhibit broad-emission lines that presumably originate in the broad-line region (BLR) with gaseous-dusty clouds in a predominantly Keplerian motion around the

Upper Limit on Brackett-γ Emission from the Immediate Accretion Flow onto the Galactic Black Hole

We present the first observational constraint on the Brackett-γ (Brγ) recombination line emission associated with the supermassive black hole at the center of our Galaxy, known as Sgr A*. By

The Picture of BLR in 2.5D FRADO: Dynamics and Geometry

The dynamics of the broad line region (BLR) in active galaxies is an open question; direct observational constraints suggest a predominantly Keplerian motion, with possible traces of inflow or



First proper motions of thin dust filaments at the Galactic center

Context. L' -band (3.8 μ m) images of the Galactic center show a large number of thin filaments in the mini-spiral, located west of the mini-cavity and along the inner edge of the Northern Arm. One

Nature of the Galactic centre NIR-excess sources. I. What can we learn from the continuum observations of the DSO/G2 source?

The Dusty S-cluster Object (DSO/G2) orbiting the supermassive black hole (Sgr A*) in the Galactic centre has been monitored in both near-infrared continuum and line emission. There has been a dispute


ALMA observations of the Galactic center with a spatial resolution of 2.″61 × 0.″97 resulted in the detection of 11 SiO (5–4) clumps of molecular gas within 0.6 pc (15″) of Sgr A*, interior to the 2

Evidence for Warped Disks of Young Stars in the Galactic Center

It is shown that half of the W-R/O stars are compatible with being members of a clockwise rotating system, which is compatible with a coherent structure such as stellar filaments, streams, small clusters or possibly a disk in a dissolving state.


We analyze and report in detail new near-infrared (1.45–2.45 μm) observations of the Dusty S-cluster Object (DSO/G2) during its approach to the black hole at the center of the Galaxy that were
