A Partial Lyman Limit Absorber in the Halo of a Galaxy Pair: A Possible Signature of Gas Inflow
Sumukha R. Bharadwaj, Anand Narayanan, Sowgat Muzahid +2
We present an analysis of a partial Lyman limit system at z = 0.87641 detected in the HST/COS spectrum of the background quasar LBQS 0107-0235. The absorber exhibits a simple kinem…
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 obtained with the Cosmic Origins Spectrograph on boar…
Environmental dependence of galaxy properties in the southern GAMA regions
Koti Joy, Unnikrishnan Sureshkumar, Anand Narayanan +4
Using data from the Galaxy and Mass Assembly (GAMA) survey, we investigate how galaxy properties correlate with the local environment, focusing on the two southern regions of the s…
Kinematic analysis of an Ultra-Strong MgII absorber at z~1.13 linking to Circumgalactic Gas Structures
Purvi Udhwani, Sameer, Anand Narayanan +3
We present a spectroscopic and imaging analysis of the ultra-strong MgII absorption system identified in the /UVES spectrum of a background quasar loc…
The SAP-1 Payload: A Technology Demonstration for Space-Based Microbiology Experiments
A Lokaveer, Vikram Khaire, Thomas Anjana +12
The SSPACE Astrobiology Payload (SAP) series, starting with the SAP-1 project is designed to conduct in-situ microbiology experiments in low earth orbit. This payload series aims t…
