Rapid Infrared Variability of Three Radio-loud Narrow-line Seyfert 1 Galaxies: A View from the Wide-field Infrared Survey Explorer
Ning Jiang, Hong-Yan Zhou, Luis C. Ho +6
Using newly released data from the Wide-field Infrared Survey Explorer, we report the discovery of rapid infrared variability in three radio-loud narrow-line Seyfert 1 galaxies (NL…
Identifying Elusive Electromagnetic Counterparts to Gravitational Wave Mergers: an end-to-end simulation
Samaya Nissanke, Mansi Kasliwal, Alexandra Georgieva
Combined gravitational-wave (GW) and electromagnetic (EM) observations of compact binary mergers should enable detailed studies of astrophysical processes in the strong-field gravi…
Supernova 2008J: early time observations of a heavily reddened SN 2002ic-like transient
F. Taddia, M. D. Stritzinger, M. M. Phillips +19
We provide additional observational evidence that some Type Ia supernovae (SNe Ia) show signatures of circumstellar interaction (CSI) with hydrogen-rich material. Early phase optic…
SDSS 0956+5128: A Broad-line Quasar with Extreme Velocity Offsets
Charles L. Steinhardt, Malte Schramm, John D. Silverman +8
We report on the discovery of a Type 1 quasar, SDSS 0956+5128, with a surprising combination of extreme velocity offsets. SDSS 0956+5128 is a broad-lined quasar exhibiting emission…
Infrared Observations of The Millisecond Pulsar Binary J1023+0038: Evidence for Short-Term Nature of Its Interacting Phase in 2000--2001
Xuebing Wang, Zhongxiang Wang, Nidia Morrell
We report our multi-band infrared (IR) imaging of the transitional millisecond pulsar system J1023+0038, a rare pulsar binary known to have an accretion disk in 2000--2001. The obs…
The absence of radio emission from the globular cluster G1
J. C. A. Miller-Jones, J. M. Wrobel, G. R. Sivakoff +9
The detections of both X-ray and radio emission from the cluster G1 in M31 have provided strong support for existing dynamical evidence for an intermediate mass black hole (IMBH) o…
