Radial velocity and atmospheric parameter calculations for the GaiaNIR spectrograph
Szabolcs Mészáros, David Hobbs, Anna Liptrott +8
Context. The upcoming GaiaNIR mission is currently planning to add a near-infrared spectrograph to its payload in order to enhance its scientific return, particularly for mapping t…
Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, A. Gómez, E. Caffau +39
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…
Gaia serial CTI modelling and radiation damage study
C. Pagani, N. C. Hambly, M. Davidson +8
During the course of its mission, ESA's Gaia spacecraft has generated a map of the stars of the Galaxy of exquisite detail. While in its L2 orbit, the satellite has been exposed to…
Towards Galactic Archaeology with Inferred Ages of Giant Stars From Gaia Spectra
Aisha S. Almannaei, Daisuke Kawata, Ioana Ciuca +4
In the era of Gaia, the accurate determination of stellar ages is transforming Galactic archaeology. We demonstrate the feasibility of inferring stellar ages from Gaia's RVS spectr…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
Diving deep into the Milky Way using Anti-Reflection Coatings for Astronomical CCDs
Anmol Aggarwal, Ashi Mittal, George M. Seabroke +1
We report two anti-reflection (AR) coatings that give better quantum efficiency (QE) than the existing AR coating on the Gaia astrometric field (AF) CCDs. Light being the core of o…
