Cold gas and a Milky Way-type 2175 Å bump in a metal-rich and highly depleted absorption system
Jingzhe Ma, Paul Caucal, Pasquier Noterdaeme +9
We report the detection of a strong Milky Way-type 2175 Å extinction bump at = 2.1166 in the quasar spectrum towards SDSS J121143.42+083349.7 from the Sloan Digital Sky Surv…
On the possibility of magnetic field detection on a microlensed source star
Ahmad Mehrabi, Habib khosroshahi, Hadi Rahmani
In a microlensing event, a large magnification occurs at caustic crossing and provides an opportunity to obtain a stronger signal associated with the object. In this paper we study…
VLT/UVES observations of extremely strong intervening damped Lyman-alpha systems: Molecular hydrogen and excited carbon, oxygen and silicon at log N(HI)=22.4
P. Noterdaeme, R. Srianand, H. Rahmani +5
We present a detailed analysis of three extremely strong intervening DLAs (log N(HI)>=21.7) observed towards quasars with VLT/UVES. We measure overall metallicities of [Zn/H]~-1.2,…
