Intensity mapping of Loeb-Rybicki haloes from scattering of galactic Lyman- emission by the diffuse intergalactic medium before reionization
Hamsa Padmanabhan, Abraham Loeb
We use the inferred evolution of Lyman- luminosities of galaxies in the redshift range of from the James Webb Space Telescope (JWST) data to predict the power spe…
Redshift space distortions in Lagrangian space and the linear large scale velocity field of dark matter
Emily Tyhurst, Hamsa Padmanabhan, Ue-Li Pen
Untangling the connection between redshift space coordinates, a velocity measurement, and three dimensional real space coordinates, is a cosmological problem that is often modeled…
An Independent Measure of the Kinematic Dipole from SDSS
Prabhakar Tiwari, Dominik J. Schwarz, Gong-Bo Zhao +3
We utilize the Sloan Digital Sky Survey (SDSS) extended Baryon Oscillation Spectroscopic Survey (eBOSS) and Baryon Oscillation Spectroscopic Survey (BOSS) catalogs with precise spe…
Cosmology with HI
Hamsa Padmanabhan
Hydrogen, the most abundant element in the Universe, has traditionally been used to investigate astrophysical processes within and around our own Galaxy. In its chemically neutral,…
Intergalactic Lyman- haloes before reionization are detectable with JWST
Hamsa Padmanabhan, Abraham Loeb
The recently reported a large population of UV luminous galaxies at high redshifts, , as well as Lyman- emitting (LAE) gala…
