Dwarf galaxy halo masses from spectroscopic and photometric lensing in DESI and DES
Helena Treiber, Alexandra Amon, Risa H. Wechsler +46
We present the most precise and lowest-mass weak lensing measurements of dwarf galaxies to date, enabled by spectroscopic lenses from the Dark Energy Spectroscopic Instrument (DESI…
Two decades of optical variability of Small Magellanic Cloud high-mass X-ray binaries
Helena Treiber, Georgios Vasilopoulos, Charles Bailyn +2
We present an analysis of the long-term optical/IR behavior of 111 high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud based on data from the OGLE collaboration. Most sy…
The AGN Optical Variability Fundamental Plane
Ashley Tarrant, Jason Hinkle, Benjamin Shappee +10
We investigate the relationship between AGN optical variability timescales, amplitudes, and supermassive black hole (SMBH) masses using homogeneous light curves from the All-Sky Au…
The Giant Accreting Protoplanet Survey (GAPlanetS): Optimization Techniques for Robust Detections of Protoplanets
Jéa I. Adams Redai, Katherine B. Follette, Jason Wang +11
High-contrast imaging has afforded astronomers the opportunity to study light directly emitted by adolescent (tens of Myr) and ``proto" (10Myr) planets still undergoing formatio…
eRASSt J040515.6-745202, an X-ray burster in the Magellanic Bridge
F. Haberl, G. Vasilopoulos, C. Maitra +13
During the third all-sky survey (eRASS3), eROSITA, the soft X-ray instrument aboard Spectrum-Roentgen-Gamma, detected a new hard X-ray transient, eRASSt J040515.6-745202, in the di…
The Giant Accreting Protoplanet Survey (GAPlanetS) -- Results from a Six Year Campaign to Image Accreting Protoplanets
Katherine B. Follette, Laird M. Close, Jared R. Males +20
Accreting protoplanets represent a window into planet formation processes. We report Hα differential imaging results from the deepest and most comprehensive accreting protoplanet s…
Revealing AGNs Through TESS Variability
Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh +7
We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision…
TESS Shines Light on the Origin of the Ambiguous Nuclear Transient ASASSN-18el
Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee +11
We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASA…
RX J0529.8-6556: a BeXRB pulsar with an evolving optical period and out of phase X-ray outbursts
H. Treiber, G. Vasilopoulos, C. D. Bailyn +12
We report the results of eROSITA and NICER observations of the June 2020 outburst of the Be/X-ray binary pulsar RX J0529.8-6556 in the Large Magellanic Cloud, along with the analys…
Chandra probes the X-ray variability of M51 ULX-7: evidence of propeller transition and X-ray dips on orbital periods
G. Vasilopoulos, F. Koliopanos, F. Haberl +4
We report on the temporal properties of the ULX pulsar M51 ULX-7 inferred from the analysis of the 2018-2020 Swift/XRT monitoring data and archival Chandra data obtained over a per…
