The Nature of the IMBH Candidate CXO~J133815.6+043255: High-Frequency Radio Emission
Krista Lynne Smith, Macon Magno, Ashutosh Tripathi
The ultra-luminous X-ray source CXO~J133815.6+043255 is a strong candidate for a bona-fide intermediate mass black hole, residing in the outskirts of NGC~5252. We present 22~GHz ra…
A Tight Correlation Between Millimeter and X-ray Emission in Accreting Massive Black Holes from <100 Milliarcsecond-resolution ALMA Observations
Claudio Ricci, Chin-Shin Chang, Taiki Kawamuro +10
Recent studies have proposed that the nuclear millimeter continuum emission observed in nearby active galactic nuclei (AGN) could be created by the same population of electrons tha…
GRB 191016A: A Long Gamma-Ray Burst Detected by TESS
Krista Lynne Smith, Ryan Ridden-Harper, Michael Fausnaugh +8
The TESS exoplanet-hunting mission detected the rising and decaying optical afterglow of GRB 191016A, a long Gamma-Ray Burst (GRB) detected by Swift-BAT but without prompt XRT or U…
Confrontation of Observation and Theory: High Frequency QPOs in X-ray Binaries, Tidal Disruption Events, and Active Galactic Nuclei
Krista Lynne Smith, Celia R. Tandon, Robert V. Wagoner
We compile observations of high-frequency quasi-periodic oscillations (QPOs) around black holes, both stellar and supermassive, and compare their positions in the parameter space o…
Spikey: Self-Lensing Flares from Eccentric SMBH Binaries
Betty X. Hu, Daniel J. D'Orazio, Zoltan Haiman +4
We examine the light curves of two quasars, motivated by recent suggestions that a supermassive black hole binary (SMBHB) can exhibit sharp lensing spikes. We model the variability…
Evidence for an Optical Low-frequency Quasi-Periodic Oscillation in the Kepler Light Curve of an Active Galaxy
Krista Lynne Smith, Richard F. Mushotzky, Patricia T. Boyd +1
We report evidence for a quasi-periodic oscillation (QPO) in the optical light curve of KIC 9650712, a narrow-line Seyfert 1 galaxy in the original Kepler field. After the developm…
