MEASUREMENT OF 21 cm BRIGHTNESS FLUCTUATIONS AT z ∼ 0.8 IN CROSS-CORRELATION (2012, background): “…redshifts are more difficult to measure, and estimates based on Mg-II lines in DLA systems observed with Hubble Space Telescope find ΩHI(z ∼ 1) ≈ (0.97 ± 0.36) × 10−3 (Rao et al. 2006), in rough agreement withz ≈ 0.2 DLA measurements (Meiring et al. 2011) and 21 cm stacking (Lah et al. 2007).”
The ESO UVES advanced data products quasar sample: II. Cosmological evolution of the neutral gas mass density (2013, methodology): “At low-redshift, results for DLAs come from the Rao et al. (2006) survey of quasars targeted because of known Mgii absorbers.”
AN EMPIRICAL CHARACTERIZATION OF EXTENDED COOL GAS AROUND GALAXIES USING Mg ii ABSORPTION FEATURES (2010, background): “The large associated HI column density (Rao et al. 2006) suggests that Mg II absorbers are similar to those H I clouds seen around individual galaxies in 21 cm surveys (e.g. Doyle et al. 2005).”
Evolution of the cosmological mass density of neutral gas from Sloan Digital Sky Survey II - Data Release 7 (2009, methodology): “Rao & Turnshek (2000) and Rao et al. (2006) used a novel technique to measure ΩDLAg at 0.1 < z < 1.6.”
THE RADIAL AND AZIMUTHAL PROFILES OF Mg ii ABSORPTION AROUND 0.5 < z < 0.9 zCOSMOS GALAXIES OF DIFFERENT COLORS, MASSES, AND ENVIRONMENTS (2011, background): “Mg II absorption originates in photo-ionized gas at temperatures around T∼ 104 K (Bergeron & Stasínska 1986; Charlton et al. 2003) with neutral Hydrogen column densities ofN(HI ) ≈ 1016 − 1022 cm2 (Churchill et al. 2000; Rigby et al. 2002; Rao et al. 2006).”
THE BIMODAL METALLICITY DISTRIBUTION OF THE COOL CIRCUMGALACTIC MEDIUM AT z ≲ 1 (2013, methodology): “For this cut-off Rao et al. (2006) argued that the DLA sample is essentially complete and therefore free of metallicity bias.”
ON THE (NON)EVOLUTION OF H i GAS IN GALAXIES OVER COSMIC TIME (2008, methodology): “Before concluding, we comment briefly on current estimates of f(NHI, X) and ρHI at z ∼ 1 where Mg II absorption has been used to identify DLA candidates (Rao & Turnshek 2000; Rao et al. 2006).”
On the Normalization of the Cosmic Star Formation History (2006, background): “The UV data atz ≤ 1 are “obscuration corrected” 1 Thanks to Sandhya Rao (Rao et al. 2006) for this terminology. by adding the FIR SFR density from Le Floc’h et al. (2005) to each point.”
A Population of Faint Extended Line Emitters and the Host Galaxies of Optically Thick QSO Absorption Systems (2007, background): “…is more than 14 times larger than that of its contemporary damped Ly systems, as estimated from the Sloan Digital Sky Survey, dN /dz(z ¼ 0:37) ¼ 0:066 (Rao et al. 2006), so even if DLAS were not larger than [O ii] emission regions, and not more numerous, only about 7% of our emitters (i.e., two…”
RADIATIVE TRANSFER IN A CLUMPY UNIVERSE. IV. NEW SYNTHESIS MODELS OF THE COSMIC UV/X-RAY BACKGROUND (2011, background): “With a power-law exponent β = 2 down to a break column of NHI = 10 21.55 cm−2 (Prochaska & Wolfe 2009), and with an incidence per unit redshift ∝ (1 + z)1.27 (Rao et al. 2006), the parameters for the DLAs becomes (A, β, γ) = (8.7× 1018, 2, 1.27).”
Four Quasars above Redshift 6 Discovered by the Canada-France High-z Quasar Survey (2007, background): “This set of absorption lines is characteristic of damped Lyα absorbers (DLAs): about 80% of the MgII systems withwrest(2796)> 1.0 Å are DLAs (Rao et al. 2006) and, moreover, all systems withwrest(2852)> 0.7 Å are DLAs (Rao & Turnshek 2000).”
THE ARECIBO LEGACY FAST ALFA SURVEY. X. THE H i MASS FUNCTION AND FROM THE 40% ALFALFA SURVEY (2010, background): “…with the value inferred from damped Lyman absorber (DLA) systems at z ∼ 2 and that significant evolution is required to reconcile measurements in the two epochs (Noterdaeme et al. 2009; Rao et al. 2006), while providing a tighter constraint on the present-day energy density of cold gas.”
