Perturbing AGN Accretion Disks with Stars and Moderately Massive Black Holes: Implications for Changing-Look AGN and Quasi-Periodic Eruptions
Sierra A. Dodd, Xiaoshan Huang, Shane W. Davis +1
We present a model that explains some extreme variability phenomena observed in active galactic nuclei (AGN). In this model, an orbiting companion interacts with the accretion disk…
Disk draining in LIGO progenitor black hole binaries and its significance to electromagnetic counterparts
Xiaoshan Huang, Sierra Dodd, Sophie Lund Schrøder +2
The effect of tidal forces on transport within a relic accretion disk in binary black holes is studied here with a suite of two-dimensional hydrodynamic simulations. As the binary…
Mid-Infrared Outbursts in Nearby Galaxies: Nuclear Obscuration and Connections to Hidden Tidal Disruption Events and Changing-Look Active Galactic Nuclei
Sierra A. Dodd, Arya Nukala, Isabelle Connor +5
We study the properties of galaxies hosting mid-infrared outbursts in the context of a catalog of five hundred thousand galaxies from the Sloan Digital Sky Survey. We find that nuc…
The Young Supernova Experiment Data Release 1 (YSE DR1): Light Curves and Photometric Classification of 1975 Supernovae
P. D. Aleo, K. Malanchev, S. Sharief +80
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry of 1…
The Circumstellar Environments of Double-Peaked, Calcium-strong Supernovae 2021gno and 2021inl
Wynn Jacobson-Galán, Padma Venkatraman, Raffaella Margutti +42
We present panchromatic observations and modeling of calcium-strong supernovae (SNe) 2021gno in the star-forming host galaxy NGC 4165 (D = 30.5 Mpc) and 2021inl in the outskirts of…
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…
Evidence for the preferential disruption of moderately massive stars by supermassive black holes
Brenna Mockler, Angela A. Twum, Katie Auchettl +4
Tidal disruption events (TDEs) provide a unique opportunity to probe the stellar populations around supermassive black holes (SMBHs). By combining light curve modeling with spectra…
The Landscape of Galaxies Harboring Changing-Look Active Galactic Nuclei in the Local Universe
Sierra A. Dodd, Jamie A. P. Law-Smith, Katie Auchettl +2
We study the properties of the host galaxies of Changing-Look Active Galactic Nuclei (CL AGNs) with the aim of understanding the conditions responsible for triggering CL activity.…
The Young Supernova Experiment: Survey Goals, Overview, and Operations
D. O. Jones, R. J. Foley, G. Narayan +68
Time domain science has undergone a revolution over the past decade, with tens of thousands of new supernovae (SNe) discovered each year. However, several observational domains, in…
