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…
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…
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…
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 ()…
