I. Ferreras, M. Tress, G. Bruzual +6
We explore variations of the dust extinction law of the Milky Way by selecting stars from the Swift/UVOT Serendipitous Source Catalogue, cross-matched with Gaia DR2 and 2MASS to pr…
The aftermath of nova Cen 2013 (V1369 Cen)
Elena Mason, Steven N. Shore, Jeremy Drake +3
Context: Classical nova progenitors are cataclysmic variables and very old novae are observed to match high mass transfer rate and (relatively) long orbital period systems. However…
An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz
M. Nicholl, T. Wevers, S. R. Oates +42
At 66 Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and iPTF16fnl. Its proximity all…
The ambiguous transient ASASSN-17hx. A possible nova-impostor
Elena Mason, Steven N. Shore, Paul Kuin +1
Some transients, although classified as novae based on their maximum and early decline optical spectra, cast doubts on their true nature and whether nova impostors might exist. We…
Dramatic change in the boundary layer in the symbiotic recurrent nova T Coronae Borealis
G. J. M. Luna, K. Mukai, J. L. Sokoloski +6
A sudden increase in the rate at which material reaches the most internal part of an accretion disk, i.e. the boundary layer, can change its structure dramatically. We have witness…
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Multiwavelength picture of the blazar S5 0716+714 during its brightest outburst
Marina Manganaro, Giovanna Pedaletti, Marlene Doert +24
S5 0716+714 is a well known BL Lac object, one of the brightest and most active blazars. The discovery in the Very High Energy band (VHE, E > 100 GeV) by MAGIC happened in 2008. In…
Decontaminating Swift UVOT Grism Observations of Transient Sources
Michael T. Smitka, Peter J. Brown, Paul Kuin +1
We present a new technique of decontaminating Swift UVOT grism spectra for transient objects. We describe the template image requirements and image processing steps necessary to su…
The Swift UVOT serendipitous source catalogue
M. Page, V. Yershov, A. Breeveld +7
We present the first Swift Ultraviolet/Optical Telescope Serendipitous Source Catalogue (UVOTSSC). The catalogue was compiled from 23,059 Swift datasets taken within the first five…
The Swift UVOT grism calibration and example spectra
Paul Kuin, Alice Breeveld, Mat Page
The calibration of the two UVOT grisms which provide slitless spectroscopy in the 170-500 nm (UV grism) and 295-660 nm (visible grism) ranges has been completed. The UV grism has a…
SOUSA: the Swift Optical/Ultraviolet Supernova Archive
Peter J. Brown, Alice A. Breeveld, Stephen Holland +2
The Ultra-Violet Optical Telescope on the Swift spacecraft has observed hundreds of supernovae, covering all major types and most subtypes. Here we introduce the Swift Optical/Ultr…
The Type IIP Supernova 2012aw in M95: hydrodynamical modelling of the photospheric phase from accurate spectrophotometric monitoring

We present an extensive optical and near-infrared photometric and spectroscopic campaign of the type IIP supernova SN 2012aw. The dataset densely covers the evolution of SN 2012aw…
Ultraviolet Observations of Super-Chandrasekhar Mass Type Ia Supernova Candidates with Swift UVOT
Peter J. Brown, Paul Kuin, Richard Scalzo +6
Among Type Ia supernovae (SNe~Ia) exist a class of overluminous objects whose ejecta mass is inferred to be larger than the canonical Chandrasekhar mass. We present and discuss the…
Hubble Space Telescope Far Ultraviolet Spectroscopy of the Recurrent Nova T Pyxidis
P. Godon, E. M. Sion, S. Starrfield +5
With six recorded nova outbursts, the prototypical recurrent nova T Pyxidis is the ideal cataclysmic variable system to assess the net change of the white dwarf mass within a nova…
