No sign of G2's encounter affecting Sgr A*'s X-ray flaring rate from observations
Elie Bouffard, Daryl Haggard, Michael A. Nowak +3
An unusual object, G2, had its pericenter passage around Sgr A*, the M supermassive black hole in the Galactic Centre, in Summer 2014. Several research teams…
First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring
The Event Horizon Telescope Collaboration
The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the phy…
High Redshift Obscured Quasars and the Need for Optical to NIR, Massively Multiplexed, Spectroscopic Facilities
Andreea Petric, Mark Lacy, Stéphanie Juneau +15
Most bulge-dominated galaxies host black holes with masses that tightly correlate with the masses of their bulges. This may indicate that the black holes may regulate galaxy growth…
Gemini Imaging of the Host Galaxies of Changing-Look Quasars
Paul J. L. Charlton, John J. Ruan, Daryl Haggard +4
Changing-look quasars are a newly-discovered class of luminous active galactic nuclei that undergo rapid (10 year) transitions between Type 1 and Type 1.9/2, with an asso…
Envisioning the next decade of Galactic Center science: a laboratory for the study of the physics and astrophysics of supermassive black holes
Tuan Do, Andrea Ghez, Jessica R. Lu +38
As the closest example of a galactic nucleus, the Galactic center (GC) presents an exquisite laboratory for learning about supermassive black holes (SMBH) and their environment. We…
Mapping the Inner Structure of Quasars with Time-Domain Spectroscopy
Yue Shen, Scott Anderson, Edo Berger +40
The ubiquitous variability of quasars across a wide range of wavelengths and timescales encodes critical information about the structure and dynamics of the circumnuclear emitting…
