GRB 130603B: No Compelling Evidence for Neutron Star Merger
Published 2015-01-01“…The near infrared (NIR) flare/rebrightening in the afterglow of the short hard gamma ray burst (SHB) 130603B measured with the Hubble Space Telescope (HST) and an alleged late-time X-ray excess were interpreted as possible evidence of a neutron star merger origin of SHBs. …”

Analysis of ∼106 Spiral Galaxies from Four Telescopes Shows Large-Scale Patterns of Asymmetry in Galaxy Spin Directions
Published 2022-01-01“…These datasets cover the Northern and Southern hemispheres, in addition to data acquired from space by the Hubble Space Telescope. The data were annotated automatically by a fully symmetric algorithm, as well as manually through a long labor-intensive process, leading to a dataset of nearly 106 galaxies. …”

The Isaac Newton Telescope Monitoring project: Stellar population in the IC 10 dwarf irregular galaxy
Published 2019-04-01“…Our data were matched to optical catalogues of Pan-STARRS (The Pan-STARRS release 1 (PS1) survey-DR1) catalogue, mid-infrared catalogue of good sources (DUSTiNGS Good Source Catalog (GSC)) from the Spitzer Space Telescope and near-IR catalogue of Hubble Space Telescope (HST). The number of 441 and 1927 were identified as C-type (carbon-rich) and M-type (oxygen-rich) stars respectively; using the matched stars between our catalogue and the HST catalogue.…”

Deep Swift/UVOT Observations of GOODS-N and the Evolution of the Ultraviolet Luminosity Function at 0.2 < z < 1.2
Published 2025-01-01“…Swift/UVOT observations probe galaxies at z ≲ 1.5 and combine a wide field of view with moderate spatial resolution; these data complement the wide-field observations of Galaxy Evolution Explorer and the deep, high-angular-resolution observations by Hubble Space Telescope. Using our catalog of detected galaxies, we calculate the UV galaxy number counts as a function of apparent magnitude and compute the UV luminosity function (LF) and its evolution with redshift. …”

Investigating the Electron-capture Supernova Candidate AT 2019abn with JWST Spectroscopy
Published 2025-01-01“…Similar to the prototypical examples of this class of objects, NGC 300 2008-OT and SN 2008S, AT 2019abn has an extremely red and dusty progenitor detected only in pre-explosion Spitzer/IRAC imaging at 3.6 and 4.5 μ m and not in deep optical or near-infrared Hubble Space Telescope images. We find that late-time observations of AT 2019abn from NEOWISE and JWST are consistent with the late-time evolution of SN 2008S. …”

An HST Transmission Spectrum of the Closest M Dwarf Transiting Rocky Planet LTT 1445Ab
Published 2025-01-01“…A mere 6.9 pc from Earth, LTT 1445A is the closest transiting M dwarf system, and its largest known planet, at 1.31 R _⊕ and 424 K, is one of the most promising targets in which to search for an atmosphere. We use Hubble Space Telescope/Wide Field Camera 3 transmission spectroscopy with the G280 and G141 grisms to study the spectrum of LTT 1445Ab between 0.2 and 1.65 μ m. …”
