WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research
A. G. Sreejith, L. Fossati, M. Lendl +81
Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…
Globular cluster Observations for Luminosity-dispersion Distances (GOLD): Project description and velocity catalogue
K. Fahrion, M. A. Beasley, A. Gvozdenko +10
We introduce and describe the Globular cluster Observations for Luminosity-Dispersion distances (GOLD) project, which has the principal aim of determining independent distances bas…
Semiresolved Stellar Populations as Distance Indicators
Ignacio Martín-Navarro, Patricia Iglesias Navarro, Francesco La Barbera +13
Galaxy distances are central to our understanding of the Universe. Despite the success of existing approaches, independent and complementary methods remain valuable for testing sys…
FASTAR -- II. Semi-resolved evolutionary stellar population models
Ignacio Martín-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +12
Standard evolutionary synthesis models rely on the assumption of a fully sampled stellar initial mass function (IMF). Under this assumption, the age, chemical composition, and IMF…
FASTAR -- I. Continuous and differentiable evolutionary stellar population models
Ignacio Martín-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +11
The development of evolutionary stellar population models is central to interpreting observations of galaxies in terms of astrophysical quantities. Stellar population models must t…
Tidal pre-conditioning and ram-pressure stripping in NGC 1427A. Deep VLT/MUSE spectroscopy and FUV-to-radio observations trace a Fornax Cluster dwarf in transformation
J. P. Carvajal, T. H. Puzia, M. Blaña +11
The early environmental transformation of low-mass cluster galaxies from gas-rich to gas-poor remains poorly constrained, partly because clear, phase-resolved observations are rare…
The complex history of NGC 1427A revealed by its star clusters and star formation history
Katja Fahrion, Michael Hilker, Avinash Chaturvedi +2
Star-forming low-mass galaxies in the dense environments of galaxy clusters provide opportunities to study how environmental effects such as ram-pressure stripping, tidal interacti…
Extragalactic archaeology through high-resolution integrated-light spectroscopy of globular clusters
M. A. Beasley, K. Fahrion, A. Gvozdenko +1
We propose to radically expand the use of extragalactic globular clusters as tools for extragalactic archaeology. We propose a large-scale spectroscopic facility to obtain high spe…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Mapping formation pathways of nuclear star clusters across galaxies
Francesca Pinna, Isabel Pérez, Anna Ferré-Mateu +21
Nuclear star clusters (NSCs) are dense, compact stellar systems only a few parsecs across, located at galaxy centers. Their small sizes make them difficult to resolve spatially. NS…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: A Low Surface Brightness Science Case
Mireia Montes, Ignacio Trujillo, David Martínez Delgado +27
The Extragalactic Low Surface Brightness (LSB, mag/arcsec) Universe represents a crucial, yet largely unseen, frontier in modern astrophysics. This faint realm…
Connecting galaxies with their haloes -- from parsec to Mpc scales
K. Fahrion, J. van de Sande, K. R. Akhil +12
Galaxy evolution is driven by processes occurring across a wide range of scales, from star formation within giant molecular clouds (parsec scales) to outflows and secular evolution…
Distance measurements from the internal dynamics of globular clusters: Application to the Sombrero galaxy (M104)
Katja Fahrion, Michael A. Beasley, Anastasia Gvozdenko +7
Globular clusters (GCs) are dense star clusters found in all massive galaxies. Recent work has established that they follow a tight relation between their internal stellar velocity…
Globular clusters in M104: Tracing kinematics and metallicities from the centre to the halo
Katja Fahrion, Michael A. Beasley, Eric Emsellem +4
As ancient star clusters, globular clusters (GCs) are regarded as powerful tracers of galaxy evolution and assembly. Due to their brightness and compact sizes, GCs are employed to…
Revisiting the globular clusters of NGC1052-DF2
K. Fahrion, M. A. Beasley, A. Gvozdenko +4
The ultra-diffuse galaxy (UDG) NGC1052-DF2 has captured the interest of astronomers ever since the low velocity dispersion measured from ten globular clusters (GCs) suggested a low…
A new way to measure the distance to NGC1052-DF2
Michael A. Beasley, Katja Fahrion, Sergio Guerra Arencibia +2
We employ a new way to measure the distance to NGC1052-DF2 via internal stellar velocity dispersions () of its globular clusters (GCs). We obtained deep (15.1h), R=18,200, Ca Tr…
