COOL-LAMPS. VII. Quantifying Strong-lens Scaling Relations with 177 Cluster-scale Strong Gravitational Lenses in DECaLS
Simon D. Mork, Michael D. Gladders, Gourav Khullar +27
We estimate the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by the ChicagO Optically selected Lenses Located At the Margins of…
A Comparison of Full Spectral Fitting Codes for Measuring the Stellar Initial Mass Function and Other Stellar Population Properties in Elliptical Galaxies
Ilaria Lonoce, Anja Feldmeier-Krause, Alexandra Masegian +1
We present a comparative test of four widely used full spectral fitting codes, with the aim of answering the question: how robust is the retrieval of the stellar initial mass funct…
The Newly Discovered Nova Super-Remnant Surrounding Recurrent Nova T Coronae Borealis: Will it Light Up During the Coming Eruption?
Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +7
A century or less separates the thermonuclear-powered eruptions of recurrent novae in the hydrogen-rich envelopes of massive white dwarfs. The colliding ejecta of successive recurr…
A 70 pc-Diameter Nova Super-remnant Surrounding the Recurrent Nova RS Ophiuchi
Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +9
Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 years, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rat…
Discovery of a Weak CN Spectral Absorption Feature in Red Supergiant Stars in the Andromeda (M31) and Triangulum (M33) Galaxies
Puragra Guhathakurta, Douglas Grion Filho, Antara R. Bhattacharya +14
Using Keck DEIMOS spectra of stars in the Andromeda (M31) and Triangulum (M33) galaxies, selected from the large multi-band (near ultraviolet, visible light, and near infrared) Hub…
COOL-LAMPS VIII: Known wide-separation lensed quasars and their host galaxies reveal a lack of evolution in since
Aidan P. Cloonan, Gourav Khullar, Kate A. Napier +36
Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the mult…
