Exploring the AGN population in protoclusters: results from the TNG300 simulation and comparison with observations

A. Traina, F. Vito, A. Pillepich +7

In this work, we investigate the physical properties and cosmic evolution of galaxies and AGN in a sample of 280 protoclusters identified in the TNG300 simulation, selected to end…

Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low

Anshuman Acharya, Satadru Bag, Sabrina Berger +29

The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…

Imaging the 21-cm Signal from the Cosmic Dawn & Epoch of Reionization and the Connection with the Global Signal

Satadru Bag, Michele Bianco, Samir Choudhuri +12

The original baseline design for SKA-Low was motivated by the ability to produce tomographic images of the redshifted 21-cm signal, thus allowing the research field to move beyond…

The host halo masses of AGNs and quasars at with TNG-Cluster, FLAMINGO and other cosmological galaxy simulations

Akanksha Kapahtia, Annalisa Pillepich, Joey Braspenning +5

Most observations and clustering analyses suggest that quasars inhabit a narrow range of dark-matter halo masses ( M) across cosmic time (). Recen…

Simulating the epoch of Helium Reionization in photon-conserving semi-numerical code SCRIPT

Akanksha Kapahtia, Tirthankar Roy Choudhury

The reionization of the second electron of helium (HeII) leaves important imprints on the thermal and ionization state of the intergalactic medium (IGM). Observational evidence sug…

Prospects of constraining reionization model parameters using Minkowski tensors and Betti numbers

Akanksha Kapahtia, Pravabati Chingangbam, Raghunath Ghara +2

We explore the possibility of constraining model parameters of the Epoch of Reionization (EoR) from 21cm brightness temperature maps, using a combination of morphological descripto…
