Spectroscopic Follow-up on Potential Magnetic Cataclysmic Variables
Spectroscopic observations of nine cataclysmic variables that have been postulated to contain magnetic white dwarfs were obtained to further characterize their classifications, orbital parameters, inclinations, and/or accretion properties.

Fermi-LAT detections of the classical novae V1723 Sco and V6598 Sgr in a multi-wavelength context
Context. Numerous classical novae have been observed to emit γ-rays (E > 100 MeV) detected by the Fermi-LAT. The prevailing hypothesis attributes this emission to the interaction of accelerated particles within shocks in the nova ejecta.

Doppler tomography of cataclysmic variables
AbstractThe study of cataclysmic variables (CVs), and in particular of the evolution of their accretion discs throughout their different brightness states, has benefited largely from the use of indirect imaging techniques. I report on the latest results obtained from Doppler tomography of CVs concentrating mainly on results published since the 2000 ...

Abstract The 2016 Brexit referendum was a watershed moment for the politicisation of the European Union (EU) in the United Kingdom. Much has been written about the politicising effects of the referendum, along with the Leave result's subsequent contestation in the media as well as in national and European election cycles.

Evolution of cataclysmic variables under different magnetic braking prescriptions
Context. The evolution of cataclysmic variables (CVs) – interacting binaries where a low-mass donor transfers matter to a white dwarf via an accretion disk – is critically controlled by magnetic braking (MB).

Cataclysmic Variables from SDSS: A Review and A Look Forward to LSST
The past and current projects of the Sloan Digital Sky Survey are reviewed in the context of applicability and results for cataclysmic variables. Ongoing and future time domain surveys that will have impact on the field are also briefly discussed.

POISONOUS IMAGES: Taranto's Environmental Crisis between the Visible and the Invisible
ABSTRACT This article explores poisonous images—images that both register and trouble the visibility of toxicity in Taranto, Italy, one of Europe's most polluted cities due to the continent's largest steel factory. Centered on photographs taken in the city's contaminated cemetery, the essay asks how slow violence can be apprehended ethnographically ...

A large HST program: effective temperatures of cataclysmic variable white dwarfs [PDF]
We present HST/COS spectroscopy for 40 cataclysmic variables (CVs), observed as part of a 122 orbit HST program. In 31 CVs, the white dwarf (WD) is recognisable through its broad Lyα absorption profile and we measure the WD effective temperatures (Teff ...
