Dissipation of AGN jets in a clumpy interstellar medium
Riju Dutta, Prateek Sharma, Kartick C. Sarkar +1
Accreting supermassive black holes (SMBHs) frequently power jets that interact with the interstellar/circumgalactic medium (ISM/CGM), regulating star-formation in the galaxy. Highl…
Feedback-Free Starbursts at Cosmic Dawn: Observable Predictions for JWST
Zhaozhou Li, Avishai Dekel, Kartick C. Sarkar +4
We extend the analysis of a physical model within the standard cosmology that robustly predicts a high star-formation efficiency (SFE) in massive galaxies at cosmic dawn due to fee…
Are Odd Radio Circles virial shocks around massive galaxies? Implications for cosmic-ray diffusion in the circumgalactic medium
Shotaro Yamasaki, Kartick C. Sarkar, Zhaozhou Li
Recently, a new population of circular radio (GHz) objects have been discovered at high Galactic latitudes, called the Odd Radio Circles (ORCs). A fraction of the ORCs encirc…
Efficient Formation of Massive Galaxies at Cosmic Dawn by Feedback-Free Starbursts
Avishai Dekel, Kartick S. Sarkar, Yuval Birnboim +2
JWST observations indicate a surprising excess of luminous galaxies at and above, consistent with efficient conversion of the accreted gas into stars, unlike the suppres…
