An Accurate Modeling of Nano-hertz Gravitational Wave Signal from Eccentric Supermassive Binary Black Holes: An Essential Step Toward a Robust Discovery

Mohit Raj Sah, Akash Maurya, Suvodip Mukherjee +7

The stochastic gravitational wave background (SGWB) in the nanohertz (nHz) regime, detectable by pulsar timing arrays (PTAs), provides a promising probe of the cosmic population of…

Imprints of Supermassive Black Hole Evolution on the Spectral and Spatial Anisotropy of Nano-Hertz Stochastic Gravitational-Wave Background

Mohit Raj Sah, Suvodip Mukherjee, Vida Saeedzadeh +3

The formation and evolution of supermassive black holes (SMBHs) remains an open question in the field of modern cosmology. The detection of nanohertz (n-Hz) gravitational waves via…

Unveiling the Galaxy Cluster - Cosmic Web Connection with X-ray observations in the Next Decade

Stephen A. Walker, Daisuke Nagai, A. Simionescu +35

In recent years, the outskirts of galaxy clusters have emerged as one of the new frontiers and unique laboratories for studying the growth of large scale structure in the universe.…

Constraining the mass density of free-floating black holes using razor-thin lensing arcs

Uddipan Banik, Frank C. van den Bosch, Michael Tremmel +5

Strong lensing of active galactic nuclei in the radio can result in razor-thin arcs, with a thickness of less than a milli-arcsecond, if observed at the resolution achievable with…

All about baryons: revisiting SIDM predictions at small halo masses

A. Bastidas Fry, F. Governato, A. Pontzen +6

We use cosmological hydrodynamic simulations to consistently compare the assembly of dwarf galaxies in both dominated, Cold (CDM) and Self--Interacting (SIDM) dark matter model…

Modeling X-ray binary evolution in normal galaxies: Insights from SINGS

P. Tzanavaris, T. Fragos, M. Tremmel +7

We present the largest-scale comparison to date between observed extragalactic X-ray binary (XRB) populations and theoretical models of their production. We construct observational…

Modeling the Redshift Evolution of the Normal Galaxy X-ray Luminosity Function

M. Tremmel, T. Fragos, B. D. Lehmer +9

Emission from X-ray binaries (XRBs) is a major component of the total X-ray luminosity of normal galaxies, so X-ray studies of high redshift galaxies allow us to probe the formatio…
