HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy
Andrew J. Fox, Jerry Kriss, Philipp Richter +49
Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectros…
Low Metallicity Gas on the Outskirts of the Local Group: the Circumgalactic Medium of Sextans B
Andrew J. Fox, Sapna Mishra, Frances H. Cashman +6
We present a UV absorption-line analysis of the circumgalactic medium (CGM) of Sextans B, a dwarf irregular galaxy at 1.3 Mpc distance on the outer frontier of the Local Group. Usi…
Discovery of Weak O VI Absorption in Underdense Regions of the Low-Redshift Intergalactic Medium
Sapna Mishra, Vikram Khaire, Romeo Pallikkara +2
We search for weak O VI absorption in the low-redshift intergalactic medium (IGM) using 82 high signal-to-noise quasar spectra from the Cosmic Origins Spectrograph on the Hubble Sp…
The LMC Corona Favors a First Passage
Scott Lucchini, Jiwon Jesse Han, Sapna Mishra +1
We use constrained idealized simulations of the LMC/Milky Way interaction to determine if the size of the LMC's gaseous halo (Corona) can be used to distinguish between first and s…
On the incidence of weak and strong Mg II absorbers towards the Flat and Steep Spectrum Radio quasars
Ritish Kumar, Sapna Mishra, Hum Chand
The incidence rate of Mg II absorbers per unit redshift path (dN/dz) towards quasar sightlines has been used to probe the interaction between quasar jets and surrounding gas clouds…
The Distance to the Magellanic Stream: Constraints from Optical Absorption along Stellar Sightlines
Sapna Mishra, Andrew J. Fox, J. V. Smoker +2
The Magellanic Stream (MS) is a large tail of neutral and ionized gas originating from tidal and hydrodynamical interactions between the Magellanic Clouds as they orbit the Milky W…
The Truncated Circumgalactic Medium of the Large Magellanic Cloud
Sapna Mishra, Andrew J. Fox, Dhanesh Krishnarao +6
The Large Magellanic Cloud (LMC) is the nearest massive galaxy to the Milky Way. Its circumgalactic medium is complex and multi-phase, containing both stripped HI structures like t…
