Science with an ngVLA: [CII] 158m Emission from Galaxies
C. L. Carilli, E. J. Murphy, A. Ferrara +1
We consider the capabilities of ALMA and the ngVLA to detect and image the[CII] 158\,m line from galaxies into the cosmic `dark ages' ( to 20). The [CII] line may pro…
The hierarchical assembly of galaxies and black holes in the first billion years: predictions for the era of gravitational wave astronomy
Pratika Dayal, Elena M. Rossi, Banafsheh Shiralilou +3
In this work we include black hole (BH) seeding, growth and feedback into our semi-analytic galaxy formation model, Delphi. Our model now fully tracks the, accretion- and merger-dr…
Probing the fluctuating Ultra-violet background using the Hubble Frontier Fields
Tirthankar Roy Choudhury, Pratika Dayal
In recent years, the rise in the number of Lyman Break Galaxies detected at high redshifts z >= 6 has opened up the possibility of understanding early galaxy formation physics in g…
Early galaxy formation and its large-scale effects
Pratika Dayal, Andrea Ferrara
Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a consensus that galaxies emerged from the expanding matter background by gravitational…
Spectroscopic investigation of a reionized galaxy overdensity at z=7
M. Castellano, L. Pentericci, E. Vanzella +17
We present deep spectroscopic follow-up observations of the Bremer Deep Field (BDF) where the two 7 bright Ly emitters (LAE) BDF521 and BDF3299 were previously discovered…
Survey parameters for detecting 21cm - Ly emitter cross correlations with the Square Kilometre Array
Anne Hutter, Cathryn M. Trott, Pratika Dayal
Detections of the cross correlation signal between the 21cm signal during reionization and high-redshift Lyman Alpha emitters (LAEs) are subject to observational uncertainties whic…
Probing the nature of Dark Matter through the metal enrichment of the intergalactic medium
Jonas Bremer, Pratika Dayal, Emma V. Ryan-Weber
We focus on exploring the metal enrichment of the intergalactic medium (IGM) in Cold and Warm (1.5 and 3 keV) Dark Matter (DM) cosmologies, and the constraints this yields on the D…
