X-ray Observations of Nova Scorpii 2023 (V1716 Sco) in Outburst
John Worley, Marina Orio, Andrej Dobrotka +5
Nova Scorpii 2023 was first detected as a luminous supersoft X-ray source (SSS) 93 days after outburst and continued emitting soft X-rays for over two months, until it was too clos…
Observing the launch of an Eddington wind in the luminous Seyfert galaxy PG1211+143
Ken Pounds, Kim Page
The luminous narrow line Seyfert galaxy PG1211+143 was the first non-BAL AGN to reveal a powerful ionized wind, based on early observations with ESA's XMM-Newton X-ray Observatory.…
Prompt Periodicity in the GRB 211211A Precursor: Black-hole or magnetar engine?
Gavin P. Lamb, Thomas Baxter, Conor M. B. Omand +18
The merger origin long GRB 211211A was a class (re-)defining event. A precursor was identified with a s separation from the main burst, as well as a claimed candidate quas…
Constraints on diffuse X-ray Emission from the TeV halo Candidate HESS J1813-126
David Guevel, Kim L Page, Kaya Mori +2
Extended regions of very high energy -ray emission associated with middle-aged pulsars have been found by -ray observatories. These regions, called TeV halos or pulsar halo…
Simultaneous multi-wavelength observations of the repeating fast radio burst FRB 20190520B with Swift and FAST
Zhen Yan, Wenfei Yu, Kim L. Page +8
Among several dozen known repeating Fast radio bursts (FRBs), those precisely localized offer the best opportunities to explore their multi-wavelength counterparts, which are key t…
Millinovae: A New Class of Transient Supersoft X-ray Sources without a Classical Nova Eruption
Przemek Mróz, Krzysztof Król, Hélène Szegedi +18
Some accreting binary systems containing a white dwarf (such as classical novae or persistent supersoft sources) are seen to emit low-energy X-rays with temperatures of ~10^6 K and…
