An outflow from the X-ray corona as the origin of millimeter emission from radio-quiet AGN
A. Hankla, A. Philippov, R. Mbarek +4
Recent observations of radio-quiet active galactic nuclei (RQAGN) have shown the presence of millimeter emission, whose origin remains unknown, from within parsec scales of the cen…

Novel Polarimetric Analysis of Near Horizon Flaring Episodes in M87* in Millimeter Wavelength
Razieh Emami, Matthew Liska, Koushik Chatterjee +15
Recent multi-wavelength observations of M87* \citep{2024A&A...692A.140A} revealed a high-energy -ray flare without a corresponding millimeter counterpart. We present a theoretic…

Magnetic flux plays an important role during a BHXRB outburst in radiative 2T GRMHD simulations
M. T. P. Liska, N. Kaaz, K. Chatterjee +2
Black hole (BH) X-ray binaries cycle through different spectral states of accretion over the course of months to years. Although fluctuations in the BH mass accretion rate are gene…
