The two young star disks in the central parsec of the galaxy: properties, dynamics and formation
We report the definite spectroscopic identification of 40 OB supergiants, giants and main sequence stars in the central parsec of the Galaxy. Detection of their absorption lines have become possibleExpand
GW151226: Observation of Gravitational Waves from a 22-Solar-Mass Binary Black Hole Coalescence.
TLDR
This second gravitational-wave observation provides improved constraints on stellar populations and on deviations from general relativity. Expand
Gravitational Waves and Gamma-Rays from a Binary Neutron Star Merger: GW170817 and GRB 170817A
On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently by the FermiExpand
Advanced LIGO
The Advanced LIGO gravitational wave detectors are second-generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments areExpand
GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1$\mathrm{M}_\odot$ during the first and second observing runs of theExpand
ASTROPHYSICAL IMPLICATIONS OF THE BINARY BLACK HOLE MERGER GW150914
The discovery of the gravitational-wave source GW150914 with the Advanced LIGO detectors provides the first observational evidence for the existence of binary black-hole systems that inspiral andExpand
AN EXTREMELY TOP-HEAVY INITIAL MASS FUNCTION IN THE GALACTIC CENTER STELLAR DISKS
We present new observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the ESO/VLT. Our work allows theExpand
Binary Black Hole Mergers in the First Advanced LIGO Observing Run
The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paperExpand
Evidence for Warped Disks of Young Stars in the Galactic Center
TLDR
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. Expand
Stellar Disk in the Galactic Center: A Remnant of a Dense Accretion Disk?
Observations of the Galactic center revealed a population of young massive stars within 0.4 pc from Sgr A*—the presumed location of a supermassive black hole. The origin of these stars is a puzzle asExpand
