Flaring Activity of Sgr A*: Expanding Hot Blobs [PDF]

, 2006
Sgr A* is considered to be a massive black hole at the Galactic center and is known to be variable in radio, millimeter, near-IR and X-rays. Recent multi-wavelength observing campaigns show a simultaneous X-ray and near-IR flare, as well as sub ...

Rotational Spectroscopy and Tentative Interstellar Detection of 3-hydroxypropanal (HOCH2CH2CHO) in the G+0.693-0.027 Molecular Cloud

The Astrophysical Journal
We synthesized the astrochemically relevant molecule 3-hydroxypropanal (HOCH _2 CH _2 CHO) and subsequently measured and analyzed its rotational spectrum in several frequency regions ranging from 130 to 485 GHz.

The Unexpected Lack of Asymmetry in the Horizon-scale Image of Sagittarius A*

The Astrophysical Journal
The ring-like images of the two supermassive black holes captured by the Event Horizon Telescope (EHT) provide powerful probes of the physics of accretion flows at horizon scales.
