A Burst of Reionization in the Dark Ages
Neal Weiner, Soubhik Kumar, Wenzer Qin +3
Primordial overdensities at small scales can be significantly larger than those observed at large scales. As a result, they can collapse much earlier, at redshifts . In…
Enhanced density fluctuations: consequences for stellar dynamics and dark matter substructure
Wenzer Qin, David E. Kaplan, Neal Weiner
Enhanced density fluctuations form early dark matter halos, which serve as early gravitational potential wells for baryons. These baryons can then condense to form stars and black…
What does it take to have at CMB times?
Miguel Escudero, Maksym Ovchynnikov, Neal Weiner
The vast majority of extensions of the Standard Model affecting the number of effective relativistic neutrino species () do so additively, namely, they enhance this qu…
Not-quite-primordial black holes
Wenzer Qin, Soubhik Kumar, Priyamvada Natarajan +1
We propose a new mechanism for the formation of seeds of supermassive black holes at early cosmic epochs. Our scenario explores density fluctuations that are enhanced relative to $…
Early Galaxies from Rare Inflationary Processes and JWST Observations
Soubhik Kumar, Neal Weiner
Rare Poisson processes (PP) during cosmic inflation can lead to signatures that are localized in position space and are not well captured by the standard two- or higher-point corre…
