Lyman- coupling and heating at Cosmic Dawn
Shikhar Mittal, Girish Kulkarni
The global 21-cm signal from the cosmic dawn is affected by a variety of heating and cooling processes. We investigate the impact of heating due to Lyman- (Ly~) photons on th…
The correlation of high-redshift galaxies with the thermal Sunyaev-Zel'dovich effect traces reionization
Eric J. Baxter, Lewis Weinberger, Martin Haehnelt +4
We explore a potential new probe of reionization: the cross-correlation of high-redshift galaxies with maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. We consider two types of…
Measurement of pure states of light in the orbital-angular-momentum basis using nine multipixel image acquisitions
Girish Kulkarni, Suman Karan, Anand K. Jha
The existing techniques for measuring high-dimensional pure states of light in the orbital angular momentum (OAM) basis either involve a large number of single-pixel data acquisiti…
Revised estimates of CMB -mode polarization induced by patchy reionization
Anirban Roy, Girish Kulkarni, P. Daniel Meerburg +4
The search for primordial gravitational waves through the -mode polarization pattern in the CMB is one of the major goals of current and future CMB experiments. Besides foregrou…
Intrinsic degree of coherence of two-qubit states and measures of two-particle quantum correlations
Nilakantha Meher, Abu Saleh Musa Patoary, Girish Kulkarni +1
Recently, a basis-invariant measure of coherence known as the intrinsic degree of coherence has been established for classical and single-particle quantum states [JOSA B {\bf 36},…
Probing the thermal state of the intergalactic medium at with the transmission spikes in high-resolution Ly forest spectra
Prakash Gaikwad, Michael Rauch, Martin G. Haehnelt +13
We compare a sample of five high-resolution, high S/N Ly forest spectra of bright QSOs aimed at spectrally resolving the last remaining transmission spikes at…
