Mapping the z>=5 SiIV Column Density Distribution onto the Galaxy Stellar Mass Function Using the Cumulative Absorption Cross Section

Kristian Finlator, Sam Patterson, Nora Nava +4

Efforts to constrain directly the activity in low-mass galaxies confront sensitivity limits even in the JWST era. Metal absorbers offer a complementary probe and are easier to dete…

Galaxy Proximate Damped Lyman-Alpha Systems and HI Reionization Topology in TECHNICOLOR DAWN

Maya Steen, Kristian Finlator, Samir Kušmić +1

Recent observations from the James Webb Space Telescope (JWST) have revealed proximate damped Lyman- systems (PDLAs) in the foreground of high redshift galaxies (), whi…

SDSS-V LVM: Verifying what, and where, the 'Galactic Center' Lobe is

K. Kreckel, O. V. Egorov, N. Drory +23

The so-called 'Galactic Center' Lobe (GCL) is an extended (~1 deg) radio continuum feature situated above the Galactic Plane, for which the literature contains varying claims about…

SDSS-V LVM: A spatially resolved study of the physical conditions and the chemical abundance discrepancy in the Lagoon Nebula (M 8)

Amrita Singh, Guillermo A. Blanc, Nimisha Kumari +19

The abundance discrepancy problem refers to the systematic differences observed between chemical abundances derived from collisionally excited lines (CELs) and recombination lines…

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…

Initial Investigations of the Outskirts of XLSSC 122

Eleanore. B. Todd, Jon. P. Willis, Rebecca. E. A. Canning +7

We investigate the redshift 1.98 galaxy cluster XLSSC 122 using the Hubble Space Telescope (HST) from the core of the cluster out to 3 Mpc, a scale equivalent to 10 times the R500…
