A Test of FeH Line Parameters using DR19 APOGEE spectra of Benchmark M Dwarfs

Anderson Silva-Andrade, Diogo Souto, Katia Cunha +9

Recent studies have suggested a mismatch of up to 0.20 dex between iron abundances derived from Fe I and FeH lines in the H-band spectra of M dwarfs, and in this work we investigat…

Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster

R. Habas, M. Cantiello, G. Riccio +169

Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…

The abundance and radial distribution of faint and ultra-faint dwarfs in galaxy clusters

Pradyumna Sadhu, Laura V. Sales, Julio F. Navarro +3

Cosmological simulations of galaxy clusters are unable to resolve dwarf galaxies due to limited numerical resolution which drives the artificial disruption of dark matter substruct…

Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey

J. V. Sales-Silva, K. Cunha, V. V. Smith +20

The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…

PAC in DESI. II. Galaxy-halo connection into the frontier

Kun Xu, Carlos S. Frenk, Y. P. Jing +37

Understanding dwarf galaxy formation is crucial for testing dark matter models and reionization physics. However, constructing stellar-mass complete spectroscopic samples at low ma…

HO in the terrestrial planet-forming regions of protoplanetary disks

Colette Salyk, Klaus M. Pontoppidan, Ke Zhang +12

Isotopologues play an important role in solar system cosmochemistry studies, revealing details of early planet formation physics and chemistry. Oxygen isotopes, as measured in sola…
