The transient event in NGC 1566 from 2017 to 2019 -- I. An eccentric accretion disk and a turbulent, disk-dominated broad-line region unveiled by double-peaked Ca II and O I lines
M. W. Ochmann, W. Kollatschny, M. A. Probst +12
NGC 1566 is known for exhibiting recurrent outbursts, which are accompanied by changes in spectral type. The most recent transient event occurred from 2017 to 2019 and was reported…
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…
Shedding far-ultraviolet light on the donor star and evolutionary state of the neutron-star LMXB Swift J1858.6-0814
N. Castro Segura, C. Knigge, J. H. Matthews +13
The evolution of accreting X-ray binary systems is closely coupled to the properties of their donor stars. As a result, we can constrain the evolutionary track a system is by estab…
The peculiar new state of the blazar PKS 1510-089
H. M. Schutte, M. Zacharias, M. Böttcher +4
Contemporaneous multiwavelength observations with H.E.S.S., SALT, Fermi-LAT, Swift, and ATOM show that the blazar PKS 1510-089 suffered a significant decrease in its optical flux,…
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)…
Long-term multiwavelength monitoring and reverberation mapping of NGC 2617 during a changing-look event
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +32
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC~2617 carried out from 2016 until 2022 and covering the wavelength range fr…
