A Possible Third Body in the X-Ray System GRS 1747-312 and Models with Higher-Order Multiplicity
Caleb Painter, Rosanne Di Stefano, Vinay L. Kashyap +7
GRS 1747-312 is a bright Low-Mass X-ray Binary in the globular cluster Terzan 6, located at a distance of 9.5 kpc from the Earth. It exhibits regular outbursts approximately every…
Pavo: Discovery of a star-forming dwarf galaxy just outside the Local Group
Michael G. Jones, Burcin Mutlu-Pakdil, David J. Sand +9
We report the discovery of Pavo, a faint (), star-forming, irregular, and extremely isolated dwarf galaxy at Mpc. Pavo was identified in Dark Energy Camera…
Discovery of An X-ray Photoionized Optical Nebula and A Radio Nebula Associated with the ULX NGC 4861 X-1
Hang Gong, Ryan Urquhart, Alexandr Vinokurov +5
We have conducted long-slit spectroscopic observations and analyzed archival radio data for the ultraluminous X-ray source (ULX) NGC 4861 X-1. Our spectral line analysis unveils th…
Catching a nova X-ray/UV flash in the visible? Early spectroscopy of the extremely slow Nova Velorum 2022 (Gaia22alz)
E. Aydi, L. Chomiuk, J. Mikołajewska +22
We present early spectral observations of the very slow Galactic nova Gaia22alz, over its gradual rise to peak brightness that lasted 180 days. During the first 50 days, when the n…
Tracking the Enigmatic Globular Cluster Ultracompact X-ray Binary X1850--087: Extreme Radio Variability in the Hard State
T. Panurach, R. Urquhart, J. Strader +6
The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850--087, located in the…
Multiwavelength Scrutiny of X-ray Sources in Dwarf Galaxies: ULXs versus AGN
Erica Thygesen, Richard M. Plotkin, Roberto Soria +10
Owing to their quiet evolutionary histories, nearby dwarf galaxies (stellar masses ) have the potential to teach us about the mechanism(s) t…
