The Close AGN Reference Survey (CARS). Long-term spectral variability study of the changing look AGN Mrk 1018
T. Saha, M. Krumpe, A. Markowitz +9
Changing-look AGNs (CLAGN) are accreting supermassive black hole systems that undergo variations in optical spectral type, driven by major changes in accretion rate. Mrk 1018 has u…
SN 1885A and supernova remnants in the centre of M31 with LOFAR
Deepika Venkattu, Peter Lundqvist, Miguel Pérez Torres +4
We present the first LOFAR image of the centre of M31 at a frequency of 150 MHz. We clearly detect three supernova remnants, which, along with archival VLA data at 3 GHz and other…
Understanding the environment around the intermediate mass black hole candidate ESO 243-49 HLX-1
N. A. Webb, A. Guérou, B. Ciambur +12
Aims. ESO 243-49 HLX-1, otherwise known as HLX-1, is an intermediate mass black hole (IMBH) candidate located 8" (3.7 Kpc) from the centre of the edge-on S0 galaxy ESO 243-49. How…
