The phenomenon of cosmological gravitational particle production (CGPP) occurs during and after inflation as quantum fields “feel” the cosmological expansion are excited out of their ground state. CGPP is a…

SPHEREx, an upcoming NASA medium-class Explorer Mission, will perform the first all-sky near infrared spectral survey. With a targeted launch date in early 2025, SPHEREx will map the entire sky at 6.2 arcsec from 0.…
Recent breakthrough observations of black holes call for a new conceptual framework that unifies their analysis, from gravitational wave production to VLBI imaging of the photon ring. I will show how this is achieved…
Current and forthcoming sky surveys promise to deliver
datasets orders of magnitude better in quality and size than their
predecessors, but our ability to take advantage of these datasets is …
This talk will have two parts. The first part concerns the mechanical wave observed in the wound healing of zebrafish tailfin. Highly regenerative animals can regrow lost appendages and the rate of regrowth is…
