Phase matching in -barium borate crystals for spontaneous parametric down-conversion
Suman Karan, Shaurya Aarav, Homanga Bharadhwaj +5
Spontaneous parametric down-conversion (SPDC) is the most widely used process for generating entangled photon pairs. In SPDC, a pump photon interacts with a nonlinear optical cryst…
Large Lyman-alpha opacity fluctuations and low CMB tau in models of late reionization with large islands of neutral hydrogen extending to z<5.5
Girish Kulkarni, Laura C. Keating, Martin G. Haehnelt +4
High-redshift QSO spectra show large spatial fluctuations in the Ly-alpha opacity of the intergalactic medium on surprisingly large scales at z>~5.5. We present a radiative transfe…
Evolution of the AGN UV luminosity function from redshift 7.5
Girish Kulkarni, Gábor Worseck, Joseph F. Hennawi
Determinations of the UV luminosity function of AGN at high redshifts are important for constraining the AGN contribution to reionization and understanding the growth of supermassi…
Lyman-alpha emitters gone missing: the different evolution of the bright and faint populations
Lewis H. Weinberger, Girish Kulkarni, Martin G. Haehnelt +2
We model the transmission of the Lyman-alpha line through the circum- and intergalactic media around dark matter haloes expected to host Lyman-alpha emitters (LAEs) at z > 5.7, usi…
Predictions and sensitivity forecasts for reionization-era [C II] line intensity mapping
Sebastian Dumitru, Girish Kulkarni, Guilaine Lagache +1
Observations of the high-redshift Universe using the 21 cm line of neutral hydrogen and complimentary emission lines from the first galaxies promise to open a new door for our unde…
