Towards a Spectro-Photometric Characterization of the Chilean Night Sky. A first quantitative assessment of ALAN across the Coquimbo Region
Rodolfo Angeloni, Juan Pablo Uchima Tamayo, Marcelo Jaque Arancibia +8
Light pollution is recognized as a global issue that, like other forms of anthropogenic pollution, has significant impact on ecosystems and adverse effects on living organisms. Mul…
Generating mock galaxy catalogues for flux-limited samples like the DESI Bright Galaxy Survey
A. Smith, C. Grove, S. Cole +28
Accurate mock galaxy catalogues are crucial to validate analysis pipelines used to constrain dark energy models. We present a fast HOD-fitting method which we apply to the AbacusSu…
Integral Field Spectroscopy: a disruptive innovation for observations of Planetary Nebulae and the PNLF
Martin M. Roth, George Jacoby, Robin Ciardullo +3
A quarter of a century has passed since the observing technique of integral field spectroscopy (IFS) was first applied to planetary nebulae (PNe). Progress after the early experime…
Ages and metallicities of stellar clusters using S-PLUS narrow-band integrated photometry: the Small Magellanic Cloud
Gabriel Fabiano de Souza, Pieter Westera, Felipe Almeida-Fernandes +14
The Magellanic Clouds are the most massive and closest satellite galaxies of the Milky Way, with stars covering ages from a few Myr up to 13 Gyr. This makes them important for vali…
Probing the early Milky Way with GHOST spectra of an extremely metal-poor star in the Galactic disk
Anya Dovgal, Kim A. Venn, Federico Sestito +31
Pristine_183.6849+04.8619 (P1836849) is an extremely metal-poor ([Fe/H]) star on a prograde orbit confined to the Galactic disk. Such stars are rare and may have their…
Precision spectrophotometry for PNLF distances: the case of NGC 300
Azlizan A. Soemitro, Martin M. Roth, Peter M. Weilbacher +5
The Multi-Unit Spectroscopic Explorer (MUSE) has enabled a renaissance of the planetary nebula luminosity function (PNLF) as a standard candle. In the case of NGC 300, we learned t…
rrlfe: Software for Generating and Applying Metallicity Calibrations for RR Lyrae Variable Stars Across a Wide Range of Phases and Temperatures
Eckhart Spalding, Ronald Wilhelm, Nathan De Lee +7
RR Lyrae stars play a central role in tracing phase-space structures within the Milky Way because they are easy to identify, are relatively luminous, and are found in large numbers…
An evolutionary continuum from nucleated dwarf galaxies to star clusters
Kaixiang Wang, Eric W. Peng, Chengze Liu +21
Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii of approximately 10-100 parsecs and stellar mas…
The UV luminosity function at 0.6 < z < 1 from UVCANDELS
Lei Sun, Xin Wang, Harry I. Teplitz +75
UVCANDELS is a HST Cycle-26 Treasury Program awarded 164 orbits of primary ultraviolet (UV) F275W imaging and coordinated parallel optical F435W imaging in four CANDELS fields: GOO…
A Spectroscopic Search for Optical Emission Lines from Dark Matter Decay
Hanyue Wang, Daniel J. Eisenstein, Jessica Nicole Aguilar +19
We search for narrow-line optical emission from dark matter decay by stacking dark-sky spectra from the Dark Energy Spectroscopic Instrument (DESI) at the redshift of nearby galaxi…
Testing the Surface Brightness Fluctuation Method on Dwarf Galaxies in the COSMOS Field
Lauren M. Foster, James E. Taylor, John P. Blakeslee
Dwarf galaxies are important tracers of small-scale cosmological structure, yet much of our knowledge about these systems comes from the limited sample of dwarf galaxies within the…
Unraveling emission line galaxy conformity at z~1 with DESI early data
Sihan Yuan, Risa H. Wechsler, Yunchong Wang +32
Emission line galaxies (ELGs) are now the preeminent tracers of large-scale structure at z>0.8 due to their high density and strong emission lines, which enable accurate redshift m…
Chemical abundances of the young inner-disk open cluster NGC 6705 observed by APOGEE: sodium-rich and not -enhanced
V. Loaiza-Tacuri, K. Cunha, D. Souto +19
Previous results in the literature have found the young inner-disk open cluster NGC 6705 to be mildly -enhanced. We examined this possibility via an independent chemical abundan…
Tracing the Galactic Disk with Planetary Nebulae using Gaia DR3
B. Bucciarelli, L. Stanghellini
We study the population of Galactic planetary Nebulae (PNe) and their central stars (CSs) through the analysis of their heliocentric distances and Galactic distribution. Distances…
