Multi-zone Modeling of Blazar Jets: Constraints from GeV-Optical Correlation and Short-Timescale Variability
Arit Bala, Kaustav Mitra, Ritaban Chatterjee
We have developed a multi-zone model of blazar jet emission, in which the emission region contains many cells with individual magnetic fields and electron energy distributions. Non…
BASILISK IV. No Tension with Satellite Kinematics
Kaustav Mitra, Frank C. van den Bosch, Josephine Baggen +1
We develop a novel technique to probe the tension, using information from the smallest scales of galaxy redshift survey data. Specifically, we use Basilisk, a Bayesian hierar…
BASILISK III. Stress-testing the Conditional Luminosity Function model
Kaustav Mitra, Frank C. van den Bosch
The Conditional Luminosity Function (CLF) is an effective and flexible way of characterizing the galaxy-halo connection. However, it is subject to a particular choice for its param…
The Impact of Baryonic Effects on the Dynamical Masses Inferred Using Satellite Kinematics
Josephine F. W. Baggen, Frank C. van den Bosch, Kaustav Mitra
Satellite kinematics offers a powerful method to infer dynamical halo masses and has been demonstrated to yield tight constraints on the galaxy-halo connection. However, previous s…
Constraining the Low Mass End of the Stellar Halo Mass Relation with Surveys of Satellite Galaxies
J. Sebastian Monzon, Frank C. van den Bosch, Kaustav Mitra
The abundance of satellite galaxies is set by the hierarchical assembly of their host halo. We leverage this to investigate the low mass end ()…
BASILISK II. Improved Constraints on the Galaxy-Halo Connection from Satellite Kinematics in SDSS
Kaustav Mitra, Frank C. van den Bosch, Johannes U. Lange
Basilisk is a novel Bayesian hierarchical method for inferring the galaxy-halo connection, including its scatter, using the kinematics of satellite galaxies extracted from a redshi…
Denser Environments Cultivate Larger Galaxies: A Comprehensive Study beyond the Local Universe with 3 Million Hyper Suprime-Cam Galaxies
Aritra Ghosh, C. Megan Urry, Meredith C. Powell +5
The relationship between galaxy size and environment has remained enigmatic, with over a decade of conflicting results. We present one of the first comprehensive studies of the var…
A candidate runaway supermassive black hole identified by shocks and star formation in its wake
Pieter van Dokkum, Imad Pasha, Maria Luisa Buzzo +13
The interaction of a runaway supermassive black hole (SMBH) with the circumgalactic medium (CGM) can lead to the formation of a wake of shocked gas and young stars behind it. Here…
Locating the GeV Emission Region in the Jets of Blazars from Months-Timescale Multi-Wavelength Outbursts
Saugata Barat, Ritaban Chatterjee, Kaustav Mitra
It is well-known that the -ray emission in blazars originate in the relativistic jet pointed at the observers. However, it is not clear whether the exact location of the GeV emi…
RMS-Flux Relation and Disc-Jet Connection in Blazars in the Context of the Internal Shocks Model
Aritra Kundu, Ritaban Chatterjee, Kaustav Mitra +1
Recent analysis of blazar variability has revealed a proportionality between the mean flux and the root mean squared (rms) fluctuations about the mean flux. Although such rms-flux…
Physical Inference from the gamma-ray, X-Ray and Optical Time Variability of a Large Sample of Fermi Blazars
Anwesh Majumder, Kaustav Mitra, Ritaban Chatterjee +3
We present cross-correlation studies of gamma-ray (0.1-300 GeV), X-ray (0.2-10 keV) and optical (R-band) variability of a sample of 26 blazars during 2008-2016. The light curves ar…
The Accretion Disc-Jet Connection in Blazars
Sagnick Mukherjee, Kaustav Mitra, Ritaban Chatterjee
The power spectral density (PSD) of the X-ray emission variability from the accretion disc-corona region of black hole X-ray binaries and active galactic nuclei has a broken power…
The Halo Occupation Distribution of Obscured Quasars: Revisiting the Unification Model
Kaustav Mitra, Suchetana Chatterjee, Michael A. DiPompeo +2
We model the projected angular two-point correlation function (2PCF) of obscured and unobscured quasars selected using the Wide-field Infrared Survey Explorer (WISE), at a median r…
Halo Occupation Distribution of Infrared Selected Quasars
Kaustav Mitra
We perform a Halo Occupation Distribution (HOD) modeling of the projected two-point correlation function (2PCF) of quasars that are observed in the Wide-field Infrared Survey Explo…
