A Standard Ultraviolet Continuum Can Hide Supercritical Accretion in GN-z11
Samik Mitra, Ramananda Santra
The ultraviolet continuum from a high-redshift accreting black hole is routinely used to infer its mass. GN-z11 offers a sharp test of whether that inference is secure. A thin-disk…
Can Isotropic Thermal Conduction Heat One of the Hottest Cool Cores?
Samik Mitra, Ramananda Santra, Norbert Werner
Thermal conduction can act as a heating mechanism for cool-core clusters, yet the same transport must erode any temperature discontinuity it crosses. Ophiuchus permits both effects…
Validating Inverse Fundamental-Plane IMBH Mass Estimates in the SKA/ngVLA Era
Shahram Abbassi, Samik Mitra, Ramananda Santra
The radio/X-ray/black-hole-mass Fundamental Plane (FP) is widely used to estimate masses of accreting intermediate-mass black hole (IMBH) candidates. Its inverse use is justified o…
Multi-Wavelength Signatures of a Giant Cometary Radio Halo in MACSJ0417-1154
Ramananda Santra, Marco Balboni, Ruta Kale
Galaxy clusters hosting diffuse non-thermal radio emission offer direct insight into plasma processes of the intracluster medium (ICM). We present the first multi-frequency study o…
Probing Merger Shocks in Galaxy Clusters in the SKA Era
Arpan Pal, Ruta Kale, Gabriella Di Gennaro +8
Galaxy cluster mergers represent the most energetic phenomena in the Universe since the Big Bang releasing gravitational potential energy of erg, injecting turbul…
Investigating particle acceleration in the Wolf-Rayet bubble NGC 2359
Anindya Saha, Anandmayee Tej, Santiago del Palacio +4
Massive stars have been proposed as candidates to be major factories of Galactic cosmic rays (GCRs). However, this claim lacks enough empirical evidence, especially for isolated st…
