We report a study of the H30α line emission at 1.3 mm from the region around Sgr A ∗ made with the Submillimeter Array at a resolution of 2 �� over a field of 60 �� (2 pc) and a velocity range of –360 to +345 km s −1 . This field encompasses most of the Galactic center’s “minispiral.” With an isothermal homogeneous Hii model, we determined the physical conditions of the ionized gas at specific locations in the Northern and Eastern Arms from the H30α line data along with Very Large Array data… Expand

The Galactic centre mini-spiral in the mm-regime
Context. The mini-spiral is a feature of the interstellar medium in the central ∼2 pc of the Galactic center. It is composed of several streamers of dust and ionised and atomic gas with temperaturesExpand
The magnetic field in the central parsec of the Galaxy
We present a polarisation map of the warm dust emission from the minispiral in the central parsec of the Galactic centre. The observations were made at a wavelength of 12.5 μm with CanariCam mountedExpand
ALMA View of the Galactic Center Minispiral: Ionized Gas Flows around Sagittarius A∗
We have observed the "Galactic center minispiral (GCMS)" in the H42α recombination line as a part of the first large-scale mosaic observation in the Sagittarius A complex using AtacamaExpand
The low-luminosity active galactic nucleus in the centre of the Galaxy
The observations of far-infrared line and continuum spectra throughout the Galactic Centre and in some regions of the disc are analysed in order to determine the physical conditions (densities, shockExpand
Identification of a high-velocity compact nebular filament 2.2 arcsec south of the Galactic Centre
The central parsec of the Milky Way is a very special region of our Galaxy; it contains the supermassive black hole associated with Sgr A* as well as a significant number of early-type stars and aExpand
ALMA Detection of Extreme Blueshifted Ionized Gas within 0.2 pc of Sgr A* from −480 to −300 km s−1
We have used the capabilities of ALMA to probe the ionized gas towards the Galactic center with the H30alpha mm hydrogen recombination line within 30'' of the Galaxy's dynamical center. TheExpand
High-speed molecular cloudlets around the Galactic center's supermassive black hole.
TLDR
It is shown that molecular cloudlets, all together with a mass of several 10 M ⊙, exist around Sgr A*. Expand
X-ray observations of the hot phase in Sagittarius A*
Context. We analyse 134 ks Chandra ACIS-I observations of the Galactic Centre (GC) performed in July 2011. The X-ray image with the field of view 17 � × 17 � contains the hot plasma surrounding theExpand
ALMA OBSERVATIONS OF THE GALACTIC CENTER: SiO OUTFLOWS AND HIGH-MASS STAR FORMATION NEAR Sgr A*
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 2Expand
Colliding winds in and around the stellar group IRS 13E at the galactic centre
IRS~13E is an enigmatic compact group of massive stars located in projection only 3.6 arcseconds away from Sgr A*. This group has been suggested to be bounded by an intermediate-mass black holeExpand
