The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + parallel Cycle 25 Hubble Space Telescope Treasury program taking data from 2018-2020. BUFFALO will expand existing coverage of the (HFF) in WFC3/IR F105W, F125W, F160W ACS/WFC F606W F814W around each six HFF clusters flanking fields. This additional area has not been observed by HST but already covered deep multi-wavelength datasets, including Spitzer Chandra. As with original program, designed to take...
Abstract One of the primary goals for upcoming James Webb Space Telescope is to observe first galaxies. Predictions planned and proposed surveys have typically focused on average galaxy counts, assuming a random distribution galaxies across observed field. The most-massive galaxies, however, are expected be tightly clustered, an effect known as cosmic variance. We show that variance likely dominant contribution uncertainty high-redshift mass luminosity functions, median high-mass counts...
A core-collapse supernova releases the vast majority of gravitational binding energy its compact remnant in form neutrinos over an interval a few tens seconds. In event within our Galaxy, multiple current and future neutrino detectors would see large burst activity. Neutrinos escape hours before light does, so any prompt information about supernova's direction that can be inferred via signal will help to enable early electromagnetic observations supernova. While there are methods determine...
Abstract With numerical simulations that employ adaptive ray-tracing (ART) for radiative transfer at the same time as evolving gas magnetohydrodynamics, thermodynamics, and photochemistry, it is possible to obtain a high-resolution view of ultraviolet (UV) fields their effects in realistic models multiphase interstellar medium. Here, we analyze results from TIGRESS-NCR simulations, which follow both far-UV (FUV) wavelengths, important photoelectric heating polycyclic aromatic hydrocarbon...
High-accuracy black hole (BH) masses require excellent spatial resolution that is only achievable for galaxies within ~100 Mpc using present-day technology. At larger distances, BH are often estimated with single-epoch scaling relations active galactic nuclei. This method requires luminosity and the velocity dispersion of broad line region (BLR) to calculate a virial product, an additional factor, $f$, determine mass. The accuracy these masses, however, unknown, there few empirical...
