ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?

Ashna Gulati, Tara Murphy, David L. Kaplan +24

We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…

Changing-Look AGN Powered By Disk Tearing

Nicholas Kaaz, Matthew Liska, Charlotte Ward +1

Changing-look active galactic nuclei (CLAGN) feature order-of-magnitude variability in both the continuum and broad line luminosities on months-to-years long timescales, and are cu…

Astrometric Jitter as a Detection Diagnostic for Recoiling and Slingshot Supermassive Black Hole Candidates

Anavi Uppal, Charlotte Ward, Suvi Gezari +4

Supermassive black holes (SMBHs) can be ejected from their galactic centers due to gravitational wave recoil or the slingshot mechanism following a galaxy merger. If an ejected SMB…

DAVOS: Dwarf Active Galactic Nuclei from Variability for the Origins of Seeds: Properties of Variability-Selected Active Galactic Nuclei in the COSMOS Field and Expectations for the Rubin Observatory

Colin J. Burke, Yichen Liu, Charlotte A. Ward +3

We study the black hole mass host galaxy stellar mass relation, , of a sample of optically-variable AGNs in the COSMOS field. The parent sample of 4…

O Corona, where art thou? eROSITA's view of UV-optical-IR variability-selected massive black holes in low-mass galaxies

R. Arcodia, A. Merloni, J. Comparat +16

Finding massive black holes (MBHs, ) in the nuclei of low-mass galaxies () is crucial to constrain seeding and…

Time-varying double-peaked emission lines following the sudden ignition of the dormant galactic nucleus AT2017bcc

E. J. Ridley, M. Nicholl, C. A. Ward +35

We present a pan-chromatic study of AT2017bcc, a nuclear transient that was discovered in 2017 within the skymap of a reported burst-like gravitational wave candidate, G274296. It…
