Cataclysmic variables from SRG/eROSITA: new systems from eRASS1
A. D. Schwope, J. Brink, D. A. H. Buckley +12
(abridged) Aims. We aim to generate large samples of CVs selected from the SRG/eROSITA surveys to address fundamental questions about binary evolution, the role of magnetic fields…
A multi-wavelength study of the 2025 low state of the intermediate polar BG CMi
A. W. Shaw, K. Mukai, C. O. Heinke +18
We present multi-wavelength observations of the first recorded low state of the intermediate polar BG CMi. Optical monitoring of the source by members of the American Association o…
The optical photometric and spectroscopic periodicities of the cataclysmic variable SRGt 062340.2-265751
J. Brink, D. A. H. Buckley, M. Veresvarska +10
We report on optical spectroscopic and photometric follow-up observations of the eROSITA discovered transient SRGt 062340.2-265751 and show that it displays the characteristics of…
The first degree-scale starlight-polarization-based tomography map of the magnetized interstellar medium
V. Pelgrims, N. Mandarakas, R. Skalidis +21
We present the first degree-scale tomography map of the dusty magnetized interstellar medium (ISM) from stellar polarimetry and distance measurements. We used the RoboPol polarimet…
A Multi-wavelength Study of Swift J0503.7-2819: a Chimeric magnetic CV
Kala G. Pradeep, Kulinder Pal Singh, G. C. Dewangan +7
We present multi-wavelength temporal and spectral characteristics of a magnetic cataclysmic variable (MCV) Swift J0503.7-2819, using far ultraviolet (FUV) and X-ray data from Astro…
Swift Deep Galactic Plane Survey Classification of Swift J170800402551.8 as a Candidate Intermediate Polar Cataclysmic Variable
B. O'Connor, E. Gogus, J. Hare +24
Here, we present the results of our multi-wavelength campaign aimed at classifying \textit{Swift} J170800402551.8 as part of the \textit{Swift} Deep Galactic Plane Survey (DGPS)…
The RoboPol sample of optical polarimetric standards
D. Blinov, S. Maharana, F. Bouzelou +34
Optical polarimeters are typically calibrated using measurements of stars with known and stable polarization parameters. However, there is a lack of such stars available across the…
X-ray properties of the white dwarf pulsar eRASSU J191213.9-441044
Axel Schwope, T. R. Marsh, Annie Standke +5
We report X-ray observations of the newly discovered pulsating white dwarf eRASSU J191213.9-441044 with Spectrum Roentgen Gamma and eROSITA (SRG/eROSITA) and XMM-Newton. The new so…
Identification of 1RXS J165424.6-433758 as a polar cataclysmic variable
B. O'Connor, J. Brink, D. A. H. Buckley +25
We present the results of our X-ray, ultraviolet, and optical follow-up campaigns of 1RXS J165424.6-433758, an X-ray source detected with the \textit{Swift} Deep Galactic Plane Sur…
Bright-Moon Sky as a Wide-Field Linear Polarimetric Flat Source for Calibration
S. Maharana, S. Kiehlmann, D. Blinov +20
Next-generation wide-field optical polarimeters like the Wide-Area Linear Optical Polarimeters (WALOPs) have a field of view (FoV) of tens of arcminutes. For efficient and accurate…
Starlight-polarization-based tomography of the magnetized interstellar medium: PASIPHAE's line-of-sight inversion method
V. Pelgrims, G. V. Panopoulou, K. Tassis +20
We present the first Bayesian method for tomographic decomposition of the plane-of-sky orientation of the magnetic field with the use of stellar polarimetry and distance. This stan…
Stokes imaging, Doppler mapping and Roche tomography of the AM Her system V834 Cen
Stephen B. Potter, E. Romero-Colmenero, C. A. Watson +2
We report on new simultaneous phase resolved spectroscopic and polarimetric observations of the polar (AM Herculis star) V834 Cen during a high state of accretion. Strong emission…
Simultaneous optical polarimetry and X-ray observations of the magnetic CV CP Tuc (AX J2315--592)
Gavin Ramsay, Stephen Potter, David Buckley +1
CP Tuc (AX J2315--592) shows a dip in X-rays which lasts for approximately half the binary orbit and is deeper in soft X-rays compared with hard X-rays. It has been proposed that t…
