The GECKOS survey: Assembly history of the lenticular galaxy NGC 3957
Yuchen Ding, Marie Martig, Ling Zhu +24
We analyse the assembly history of the edge-on lenticular galaxy NGC 3957 using deep integral-field spectroscopic MUSE data from the GECKOS survey. By applying a dust-corrected Mul…
Theoretical emission lines and metallicity calibrations of H II regions in ASTRID simulation
Yao Yao, Kathryn Grasha, Stuart Wyithe +5
We present a theoretical framework to derive redshift-dependent metallicity calibrations for galaxies at =2-7. The ionization parameter () and gas pressure () in our appro…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Optical Variability Structure Function of Low-Luminosity AGN using ATLAS Lightcurves
Ashley Hai Tung Tan, Christian Wolf, Neelesh Amrutha +3
The origin of the optical flux variability in active galactic nuclei (AGN) is largely unknown. Previous studies have correlated features of the variability structure function (SF)…
Investigating the role of turbulence in the interstellar medium in dusty star-forming galaxies using kpc-resolution ALMA dust and gas maps
B. A. Westoby, J. A. Hodge, P. Sharda +28
We present ALMA high-resolution (0.25/2 kpc) CO(5-4) and CO(4-3) observations of three submillimetre-selected dusty galaxies from the ALESS survey.…
Global asteroseismology of 19,000 red giants in the TESS Continuous Viewing Zones
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
TESS (Transiting Exoplanet Survey Satellite) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19,151 r…
