Accretion-disk sizes in two quasars with interferometrically resolved broad-line regions at and
Francisco Pozo Nuñez, Eduardo Bañados, Swayamtrupta Panda +3
We present the first direct comparison between accretion-disk (AD) and broad-line region (BLR) sizes in quasars at z > 2, combining continuum reverberation mapping with interferome…
HALO II: Constraining Hubble constant through continuum delay fitting of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +28
The Hubble tension remains one of the most significant unresolved problems in modern cosmology. A key question is whether it may arise from underestimated systematic uncertainties…
Radiation Pressure Instability in the "turn-on" Changing-Look AGN SDSS J1430+2303
Han He, Bei You, Marzena Śniegowska +3
We aim to investigate the multi-wavelength variability, spectral, and timing properties of the changing-look active galactic nucleus (CL AGN) SDSS J1430+2303, and to explore the ph…
Traversing the Galactic Centre in space and time
Michal Zajaček, Bożena Czerny, Martin Mondek +5
The Galactic Center is often identified with its central supermassive black hole, Sgr A*. Yet the black hole governs gravitationally only the innermost few parsecs of the Milky Way…
Tidal disruption of a low-mass star in an active galactic nucleus as the origin of the PS16dtm outburst
Marzena Śniegowska, Bożena Czerny, Michal Zajaček +7
The event PS16dtm, which occured in the center of the Narrow Line Seyfert 1 (NLS1) galaxy SDSS J015804.75-005221.8 (z = 0.080440), is one of the few candidates for a tidal disrupti…
A Changing-Look Seyfert Discovered by eROSITA Reveals a Two-Component Broad-Line Region
Alex Markowitz, Mirko Krumpe, David Homan +12
Extreme sudden changes in the flow of accreting gas onto SMBHs manifest themselves via large-amplitude continuum variability and changes to broad Balmer emission profiles, driving…
