Multi-Band Optical Variability Characteristics of the -ray emitting blazar 1ES 0647+250 during its 2020 flare
K. Subbu Ulaganatha Pandian, C. S. Stalin, S. Muneer +4
We present a multi-band optical variability study of the -ray emitting high-synchrotron-peaked blazar 1ES~0647+250 during its enhanced optical activity in 2020. The analysis uti…
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…
Consistency between X-ray and UV-Optical reverberation measurements in NGC 5548
Amit Kumar Mandal, Bożena Czerny, Michal Dovčiak +2
The hard X-rayemitting hot corona is a key component of active galaxies. Constraints on the hot corona height can be derived from reverberation studies in both the X-ray and opt…
Ultraviolet variability in Radio-Loud Active Galactic Nuclei observed by UVIT onboard AstroSat
M. Reshma, C. S. Stalin, Amit Kumar Mandal +3
Radio-loud active galactic nuclei (AGN) are among the most luminous objects in the Universe, emitting radiation from low-energy radio waves to high energy -rays. They are well k…
