Chemical Compositions of Red Giant Stars from Habitable Zone Planet Finder Spectroscopy

Christopher Sneden, Melike Afsar, Zeynep Bozkurt +15

We have used the Habitable Zone Planet Finder (HPF) to gather high resolution, high signal-to-noise near-infrared spectra of 13 field red horizontal-branch (RHB) stars, one open-cl…

Towards a physical understanding of the thermal background in large ground-based telescopes

Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11

Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…

First Co-spatial Comparison of Stellar, Neutral-, and Ionized-gas Metallicities in a metal-rich galaxy: M83

Svea Hernandez, Alessandra Aloisi, Bethan L. James +14

We carry out a comparative analysis of the metallicities from the stellar, neutral-gas, and ionized-gas components in the metal-rich spiral galaxy M83. We analyze spectroscopic obs…

Probing frequency-dependent half-wave plate systematics for CMB experiments with full-sky beam convolution simulations

Adriaan J. Duivenvoorden, Alexandre E. Adler, Matteo Billi +2

We study systematic effects from half-wave plates (HWPs) for cosmic microwave background (CMB) experiments using full-sky time-domain beam convolution simulations. Using an optical…

Accretion disc cooling and narrow absorption lines in the tidal disruption event AT 2019dsg

G. Cannizzaro, T. Wevers, P. G. Jonker +23

We present the results of a large multi-wavelength follow-up campaign of the Tidal Disruption Event (TDE) \dsg, focusing on low to high resolution optical spectroscopy, X-ray, and…

Luminous Red Nova AT 2019zhd, a new merger in M 31

A. Pastorello, M. Fraser, G. Valerin +20

We present the follow-up campaign of the luminous red nova (LRN) AT~2019zhd, the third event of this class observed in M 31. The object was followed by several sky surveys for abou…
