A Multiwavelength Portrait of the 3C 220.3 Lensed System

Sóley Ó. Hyman, Belinda J. Wilkes, S. P. Willner +10

The 3C 220.3 system is a rare case of a foreground narrow-line radio galaxy ("galaxy A," ) lensing a background submillimeter galaxy (). New spe…

Light and colour of cirrus, translucent and opaque dust in the high-latitude area of LDN 1642

K. Mattila, P. Väisänen, K. Lehtinen +2

We have performed a 5-colour surface photometric study of the high-galactic-latitude area of dark nebula LDN 1642. Scattered light properties are presented of diffuse, translucent…

Powerful Radio-Loud Quasars are Triggered by Galaxy Mergers in the Cosmic Bright Ages

Peter Breiding, Marco Chiaberge, Erini Lambrides +14

While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) drivi…

Wavelength-resolved reverberation mapping of intermediate redshift quasars HE 0413-4031 and HE 0435-4312: Dissecting Mg II, optical Fe II, and UV Fe II emission regions

Raj Prince, Michal Zajaček, S. Panda +24

We present the wavelength-resolved reverberation mapping (RM) of combined MgII and UV FeII broad-line emissions for two intermediate redshifts (z1), luminous quasars - HE 041…

Wavelength-resolved Reverberation Mapping of quasar CTSC30.10: Dissecting MgII and FeII emission regions

Raj Prince, Michal Zajaček, Bożena Czerny +20

We present the results of the reverberation monitoring aimed at MgII broad line and FeII pseudocontinuum for the luminous quasar CTS C30.10 (z = 0.90052) with the Southern African…

An absolute calibration of the near-infrared Period-Luminosity Relations of Type II Cepheids in the Milky Way and in the Large Magellanic Cloud

Piotr Wielgórski, Grzegorz Pietrzyński, Bogumił Pilecki +29

We present time-series photometry of 21 nearby Type II Cepheids in the near-infrared J, H and Ks passbands. We use this photometry, together with the Third Gaia Early Data Release…
