Multiwavelength study of extreme variability in LEDA 1154204: A changing-look event in a type 1.9 Seyfert
T. Saha, A. Markowitz, D. Homan +16
Context. Multiwavelength studies of transients in actively accreting supermassive black holes have revealed that large-amplitude variability is frequently linked to significant cha…
Integral Field Spectroscopy of 13 Tidal Disruption Event Hosts from the ZTF Survey
Erica Hammerstein, S. Bradley Cenko, Suvi Gezari +6
The host galaxies of tidal disruption events (TDEs) have been shown to possess peculiar properties, including high central light concentrations, unusual star-formation histories, a…
Probing the Origin of Changing-look Quasar Transitions with Chandra
Qian Yang, Paul J. Green, Chelsea L. MacLeod +9
Extremely variable quasars can also show strong changes in broad-line emission strength and are known as changing-look quasars (CLQs). To study the CLQ transition mechanism, we pre…
The Time Domain Spectroscopic Survey: Changing-Look Quasar Candidates from Multi-Epoch Spectroscopy in SDSS-IV
Paul J. Green, Lina Pulgarin-Duque, Scott F. Anderson +18
Active galactic nuclei (AGN) can vary significantly in their rest-frame optical/UV continuum emission, and with strong associated changes in broad line emission, on much shorter ti…
The nascent milliquasar VT J154843.06+220812.6: tidal disruption event or extreme accretion-state change?
Jean J. Somalwar, Vikram Ravi, Dillon Dong +5
We present detailed multiwavelength follow up of a nuclear radio flare, VT J154843.06+220812.6, hereafter VT J1548. VT J1548 was selected as a mJy radio flare in 3 GHz ob…
Search for a Dark Photon in Electro-Produced Pairs with the Heavy Photon Search Experiment at JLab
P. H. Adrian, N. A. Baltzell, M. Battaglieri +74
The Heavy Photon Search experiment took its first data in a 2015 engineering run using a 1.056 GeV, 50 nA electron beam provided by CEBAF at the Thomas Jefferson National Accelerat…
Search for a Dark Photon in Electro-Produced Pairs with the Heavy Photon Search Experiment at JLab
P. H. Adrian, N. A. Baltzell, M. Battaglieri +74
The Heavy Photon Search experiment took its first data in a 2015 engineering run at the Thomas Jefferson National Accelerator Facility, searching for a prompt, electro-produced dar…
Dark Sectors 2016 Workshop: Community Report
Jim Alexander, Marco Battaglieri, Bertrand Echenard +201
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the…
Search for a new gauge boson in the Experiment (APEX)
S. Abrahamyan, Z. Ahmed, K. Allada +63
We present a search at Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling to electrons. Such a particle can be produced in electron-…
