Stellar associations - groups of coeval, co-moving stars - are fundamental to our understanding of stellar ages and critical for the study of stellar and planetary evolution. All stellar age measurements, with the sole exception of the Sun, are based … Read more
Physics From the Ground Up - our monthly talk series hosted at Lanza's Cafe aimed at presenting exciting physics research to the general public.
Modern synoptic sky surveys are typically designed to detect supernovae-like transients, using a tiling strategy to identify objects that evolve on day-to-month timescales. Astrophysical phenomena with sub-hour durations, ranging from galactic stellar flares to optical flashes accompanying gamma-ray bursts, have … Read more
Extreme Photonics with Nanogap Cavities: From Ultrafast Single Photon Sources to Biosensors Maiken H. Mikkelsen Department of Electrical and Computer Engineering, Duke University, USA Abstract: Nano- and quantum materials with unique optical properties hold the potential for … Read more

Altering the Pre-recombination Expansion History with Hidden Sector Decays Many cosmological models introduce a new energy density contribution to the universe before the epoch of recombination in an attempt to alter the expansion history and address the Hubble tension: a 5σ discrepancy … Read more
Julian Munoz, Harvard University Cosmic Dawn: The next frontier in cosmology The last decades have firmly established the existence of a dark sector of our universe. Yet, details of its content have evaded all laboratory probes. In this talk I … Read more
Constraining Dark Matter Candidates in Early Matter Dominated Era Cosmologies An early matter dominated era (EMDE) before the onset of the radiation dominated era (RDE) is a prediction of many early Universe theories. Subhorizon dark matter (DM) density perturbations grow … Read more
