Time Delay of MgII Emission Response for the Luminous Quasar HE 0435-4312: Towards Application of High-Accretor Radius-Luminosity Relation in Cosmology
Michal Zajaček, Bożena Czerny, Mary Loli Martinez-Aldama +21
Using the six years of the spectroscopic monitoring of the luminous quasar HE 0435-4312 () with the Southern African Large Telescope (SALT), in combination with the photo…
Time-delay measurement of MgII broad line response for the highly-accreting quasar HE 0413-4031: Implications for the MgII-based radius-luminosity relation
Michal Zajaček, Bożena Czerny, Mary Loli Martinez-Aldama +16
We present the monitoring of the AGN continuum and MgII broad line emission for the quasar HE 0413-4031 () based on the six-year monitoring by the South African Large Teles…
Time delay measurement of Mg II line in CTS C30.10 with SALT
Bozena Czerny, Aleksandra Olejak, Mateusz Ralowski +18
We report 6 yr monitoring of a distant bright quasar CTS C30.10 (z = 0.90052) with the Southern African Large Telescope (SALT). We measured the rest-frame time-lag of da…
Machine-learning identification of galaxies in the WISExSuperCOSMOS all-sky catalogue
T. Krakowski, K. Małek, M. Bilicki +3
The two currently largest all-sky photometric datasets, WISE and SuperCOSMOS, were cross-matched by Bilicki et al. (2016) (B16) to construct a novel photometric redshift catalogue…
Towards automatic classification of all WISE sources
Agnieszka Kurcz, Maciej Bilicki, Aleksandra Solarz +3
The WISE satellite has detected hundreds of millions sources over the entire sky. Classifying them reliably is however a challenging task due to degeneracies in WISE multicolour sp…
The mass of the black hole in RE J1034+396
B. Czerny, B. You, A. Kurcz +6
The black hole mass measurement in active galaxies is a challenge, particularly in sources where the reverberation method cannot be applied. We aim to determine the black hole mass…
Automatised classification of WISE sources: first results, future prospects
Agnieszka Kurcz, Magdalena Krupa, Maciej Bilicki +3
We present the first results of our dedicated programme of automatised classification of galaxies, stars and quasars in the mid-infrared all-sky data from the WISE survey. We emplo…
Learning algorithms at the service of WISE survey
Katarzyna Małek, Tomasz Krakowski, Maciej Bilicki +4
We have undertaken a dedicated program of automatic source classification in the WISE database merged with SuperCOSMOS scans, comprehensively identifying galaxies, quasars and star…
The dust origin of the Broad Line Region and the model consequences for AGN unification scheme
Bozena Czerny, Justyna Modzelewska, Francesco Petrogalli +7
We propose a very simple physical mechanism responsible for the formation of the Low Ionization Line part of the Broad Line Region in Active Galactic Nuclei. It explains the scalin…
