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...
Stars stripped of their hydrogen-rich envelopes through binary interaction are thought to be responsible for both hydrogen-poor supernovae and the hard ionizing radiation observed in low-Z galaxies. A population these stars was recently first time, but prevalence remains unknown. In preparation such measurements, we estimate mass distribution hot, using a synthesis code that interpolates over detailed single stellar evolution tracks. We predict constant star formation rate $1 ,M_⊙$/yr...
Our understanding of galaxy evolution is derived from large surveys designed to maximize efficiency by only observing the minimum amount needed infer properties for a typical galaxy. However, few percent galaxies in every survey, these observations are insufficient and can be catastrophically wrong. Further, it currently difficult or impossible determine which objects have failed, so that contaminate study properties. We develop novel method identify combining astronomical codes with...
Abstract Polar faculae are the footpoints of magnetic-field lines near Sun’s poles that seen as bright regions along edges granules. The time variation in number polar has been shown to correlate with strength magnetic field and be a predictor subsequent solar cycle. Due small size transient nature these features, combined different techniques observational factors, previous counts differ magnitude. Further, there were no scalable measure statistical properties faculae, such facular lifetime...
Abstract Coronal mass ejections (CMEs) are energetic releases of large‐scale magnetic structures from the Sun. CMEs can have impacts on spacecraft and at Earth. This trajectory is typically assumed to be radial, but often CME moves outward with some spatial offset source region where eruption initially occurred. A frequently accompanied by a prominence eruption, movement cool, dense material up into corona that ejected or fall back down. We investigate eruptions in which portion falls Sun...
Stars stripped of their hydrogen-rich envelopes through binary interaction are thought to be responsible for both hydrogen-poor supernovae and the hard ionizing radiation observed in low-$Z$ galaxies. A population these stars was recently first time, but prevalence remains unknown. In preparation such measurements, we estimate mass distribution hot, using a synthesis code that interpolates over detailed single stellar evolution tracks. We predict constant star-formation rate $1 \,M_\odot$/yr...
