Detecting PAHs in high-z galaxies in proxy: Modelling physical conditions in an extremely strong damped Lyman-alpha absorber towards QSO SDSS J1143+1420 at z=2.323
Gargi Shaw, A. Ranjan
We explore indirect methods to detect Polycyclic Aromatic Hydrocarbons (PAHs) in gas-rich, absorption-selected galaxies at high redshift. We look at the optical VLT/X-shooter obser…
Multi-phase gas properties of extremely strong intervening DLAs towards quasars
A. Ranjan, R. Srianand, P. Petitjean +6
We present the results of a spectroscopic analysis of extremely strong damped Lyman-α absorbers (ESDLAs, log N(Hi)>=21.7) observed with VLT-XShooter. ESDLAs probe gas from within t…
Extremely strong DLAs at high redshift: Gas cooling and H formation
K. N. Telikova, S. A. Balashev, P. Noterdaeme +2
We present a spectroscopic investigation with VLT/X-shooter of seven candidate extremely strong damped Lyman- absorption systems (ESDLAs, cm$^{…
Thomson and Collisional Regimes of In-Phase Coherent Microwave Scattering Off Gaseous Microplasmas
Adam R. Patel, Apoorv Ranjan, Xingxing Wang +3
The total number of electrons in a classical microplasma can be non-intrusively measured through elastic in-phase coherent microwave scattering (CMS). Here, we establish a theoreti…
The properties and environment of very young galaxies in the local Universe
M. Trevisan, G. A. Mamon, T. X. Thuan +3
In the local Universe, there is a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a lar…
Chemical enrichment and host galaxies of extremely-strong intervening DLAs towards quasars
A. Ranjan, P. Noterdaeme, J. -K. Krogager +5
We present the results from VLT/X-shooter spectroscopic observations of 11 extremely strong intervening damped Lyman-alpha absorbers (ESDLAs) initially selected as high N(Hi) (i.e.…
