The Swansong of the Galactic Center Source X7: An Extreme Example of Tidal Evolution near the Supermassive Black Hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +14
We present two decades of new high-angular-resolution near-infrared data from the W. M. Keck Observatory that reveal extreme evolution in X7, an elongated dust and gas feature, pre…
AIROPA II: Modeling Instrumental Aberrations for Off-Axis Point Spread Functions in Adaptive Optics
Anna Ciurlo, Paolo Turri, Gunther Witzel +12
Images obtained with single-conjugate adaptive optics (AO) show spatial variation of the point spread function (PSF) due to both atmospheric anisoplanatism and instrumental aberrat…
Optical and NIR data and modelling of nova V5668 Sgr
L. Takeda, M. Diaz, R. D. Campbell +4
We present HST optical images, Keck-OSIRIS NIR IFS data cubes and Keck-NIRC2 NIR images of nova V5668 Sgr from 2016 to 2019. The observations indicate enhanced emission at the pola…
Upper Limit on Brackett-gamma Emission from the Immediate Accretion Flow onto the Galactic Black Hole
Anna Ciurlo, Mark R. Morris, Randall D. Campbell +3
We present the first observational constraint on the Br-gamma recombination line emission associated with the supermassive black hole at the center of our Galaxy, known as Sgr A*.…
A population of dust-enshrouded objects orbiting the Galactic black hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +9
The central 0.1 parsecs of the Milky Way host a supermassive black hole identified with the position of the radio and infrared source Sagittarius A*, a cluster of young, massive st…
A Potential Progenitor for the Type Ic Supernova 2017ein
Charles D. Kilpatrick, Tyler Takaro, Ryan J. Foley +9
We report the first detection of a credible progenitor system for a Type Ic supernova (SN Ic), SN 2017ein. We present spectra and photometry of the SN, finding it to be similar to…
