    • Damped ly alpha absorbers in star-forming galaxies at z < 0.15 Detected with the Hubble Space Telescope and ... 
      Kulkarni, Varsha P.; Bowen, David; Straka, Lorrie A.; York, Donald G.; Gupta, Neeraj; Noterdaeme, Pasquier; Srianand, Raghunathan (IOP, 2022)
      We report Hubble Space Telescope Cosmic Origins Spectrograph spectroscopy of 10 quasars with foreground starforming galaxies at 0.02 < z < 0.14 within impact parameters of ∼1–7 kpc. We detect damped/sub-damped Lyα (DLA/sub-DLA) ...

      The Cosmology Large Angular Scale Surveyor (CLASS) is a four-telescope array observing the largest angular scales (2 ℓ  200) of the cosmic microwave background (CMB) polarization. These scales encode information ...
