ASASSN-14ko is a Periodic Nuclear Transient in ESO 253-G003
Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle +24
We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated Survey for S…
Detection of Extensive Optical Emission from the Extremely Radio Faint Galactic Supernova Remnant G182.4+4.3
Robert Fesen, Jack Neustadt, Thomas How +1
Wide-field Halpha images of the radio faint Galactic supernova remnant G182.4+4.2 reveal a surprisingly extensive and complex emission structure, with an unusual series of broad an…
Discovery and Early Evolution of ASASSN-19bt, the First TDE Detected by TESS
Thomas W. -S. Holoien, Patrick J. Vallely, Katie Auchettl +22
We present the discovery and early evolution of ASASSN-19bt, a tidal disruption event (TDE) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) at a distance of $d\…
Optical Emission Associated with the Galactic Supernova Remnant G179.0+2.6
Thomas How, Robert Fesen, Jack Neustadt +2
Narrow passband optical images of the large Galactic supernova remnant G179.0+2.6 reveal a faint but nearly complete emission shell dominated by strong [O III] 4959,5007 A line emi…
A Distance Estimate to the Cygnus Loop Based on the Distances to Two Stars Located Within the Remnant
Robert A. Fesen, Jack M. M. Neustadt, Christine S. Black +1
Underlying nearly every quantitative discussion of the Cygnus Loop supernova remnant is uncertainty about its distance. Here we present optical images and spectra of nebulosities a…
