Chemical enrichment of stars due to accretion from ISM during the Galaxy's assembly
Sijing Shen, Girish Kulkarni, Piero Madau +1
Using the Eris zoom-in cosmological simulation of assembly of a Milky Way analog, we study chemical enrichment of stars due to accretion of metal-enriched gas from the interstellar…
Single-shot measurement of the orbital-angular-momentum spectrum of light
Girish Kulkarni, Rishabh Sahu, Omar S. Magana-Loaiza +2
The existing methods for measuring the orbital-angular-momentum (OAM) spectrum suffer from issues such as poor efficiency, strict interferometric stability requirements, and too mu…
Constraints on the evolution of the relationship between HI mass and halo mass in the last 12 Gyr
Hamsa Padmanabhan, Girish Kulkarni
The neutral hydrogen (HI) content of dark matter haloes forms an intermediate state in the baryon cycle that connects the hot shock-heated gas and cold star-forming gas in haloes.…
Models of the Cosmological 21 cm Signal from the Epoch of Reionization Calibrated with Lyman-alpha and CMB Data
Girish Kulkarni, Tirthankar Roy Choudhury, Ewald Puchwein +1
We present here 21 cm predictions from high dynamic range simulations for a range of reionization histories that have been tested against available Lyman-alpha and CMB data. We ass…
