GRB 220706A: a gamma-ray burst with a month-long engine and a luminous supernova
Benjamin P. Gompertz, Nusrin Habeeb, Dheeraj R. Pasham +30
While the progenitors of many long gamma-ray bursts (GRBs) are well established as the core collapse of very massive, envelope-stripped, rapidly-rotating stars, it has been suggest…
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…
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 halos,…
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…
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…
Mixing of hot shocked plasma with cold gas in Nova YZ Ret 2020
Sharon Mitrani, Ehud Behar, Jeremy J. Drake +5
The origin of bright X-ray emission lines that appear late in a nova eruption remains largely a puzzle. We present two high-resolution X-ray grating spectra of the classical nova Y…
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…
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.…
Chandra High Energy Transmission Gratings Spectra of V3890 Sgr
Marina Orio, Jeremy J. Drake, Jan-Uwe Ness +13
The recurrent nova (RN) V3890 Sgr was observed during the 7th day after the onset of its most recent outburst, with the Chandra ACIS-S camera and High Energy Transmission Gratings…
The unusual X-ray emission of the short Swift GRB 090515: Evidence for the formation of a magnetar?
A. Rowlinson, P. T. O'Brien, N. R. Tanvir +16
The majority of short gamma-ray bursts (SGRBs) are thought to originate from the merger of compact binary systems collapsing directly to form a black hole. However, it has been pro…
GRB 090926A and Bright Late-time Fermi LAT GRB Afterglows
C. A. Swenson, A. Maxham, P. W. A. Roming +10
GRB 090926A was detected by both the GBM and LAT instruments on-board the Fermi Gamma-Ray Space Telescope. Swift follow-up observations began ~13 hours after the initial trigger. T…
The Spectral Energy Distribution of Fermi bright blazars
A. A. Abdo, M. Ackermann, M. Ajello +107
(Abridged) We have conducted a detailed investigation of the broad-band spectral properties of the γ-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS). By combining ou…
Optical and X-ray Observations of M31N 2007-12b: An Extragalactic Recurrent Nova with a Detected Progenitor?
M. F. Bode, M. J. Darnley, A. W. Shafter +4
We report combined optical and X-ray observations of nova M31N 2007-12b. Optical spectroscopy obtained 5 days after the 2007 December outburst shows evidence of very high ejection…
GRB 061121: Broadband spectral evolution through the prompt and afterglow phases of a bright burst
K. L. Page, R. Willingale, J. P. Osborne +33
Swift triggered on a precursor to the main burst of GRB 061121 (z=1.314), allowing observations to be made from the optical to gamma-ray bands. Many other telescopes, including Kon…
Swift and optical observations of GRB 050401
Massimiliano De Pasquale, Andy P. Beardmore, S. D. Barthelmy +22
We present the results of the analysis of gamma-ray and X-ray data of GRB 050401 taken with the Swift satellite, together with a series of ground-based follow-up observations. The…
