REQUIEM-2D: Spatially Resolved Stellar Populations from HST 2D Grism Spectroscopy

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Mohammad Akhshik, Katherine E. Whitaker, Gabriel Brammer, Guillaume Mahler, Keren Sharon | Summary: We present a novel Bayesian methodology to jointly model photometry and deep Hubble Space Telescope (HST) 2d grism spectroscopy of high-redshift galaxies. Our requiem2d code measures both unresolved and resolved stellar populations, ages, […]

Low Energy Spread Attosecond Bunching and Coherent Electron Acceleration in Dielectric Nanostructures

Kavli Affiliate: Robert Byer | Summary:We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon structures. Unlike previous ballistic optical microbunching demonstrations, we use a modulator-demodulator scheme to compress phase space in the time […]

Enhanced bivariant homology theory attached to six functor formalism

Kavli Affiliate: Tomoyuki Abe | Summary:Bivariant theory is a unified framework for cohomology and Borel-Moore homology theories. In this paper, we extract an $infty$-enhanced bivariant homology theory from Gaitsgory-Rozenblyum’s six functor formalism. | Search Query: arXiv Query: search_query=au:”Abe Tomoyuki”&id_list=&start=0&max_results=10Read More
