N/O-enhanced chemical enrichment by massive stars: the interplay of optically-thick winds and rotation
Recent JWST observations have revealed a sample of high-$z$ galaxies with highly-enhanced N/O abundance ratios, $\log\rm (N/O)\gtrsim -1.1$.A Multiband Catalog of Infrared-Excess Sources in the Vela-Carina Region: VVVX, DECaPS, and GLIMPSE
Multiwavelength surveys of the Galactic midplane enable the identification of infrared-excess sources, signatures of circumstellar material, though high extinction and crowding hinder detection.New Optical and Mid-Infrared RR Lyrae Period-Luminosity-Metallicity Relations for Precision Distances and Metallicity Distributions in the Magellanic Clouds
RR Lyrae (RRL) stars, thanks to the existence of their period-luminosity relations, have been widely used as primary standard candles within the Milky Way and the Local Group of galaxies.Sequential Star-Formation and the Near-Infrared Stellar Populations within N159
We present the first results from a JWST/NIRCam study of the star-forming region N159, one of the richest H II complexes in the Large Magellanic Cloud.Super-Resolution of Solar Magnetograms via Adaptive Stratified Ensemble Learning with Uncertainty Estimation
Single-image super-resolution of Sun's photospheric magnetograms enables consistent analysis across heterogeneous space-based instruments and supports long-term studies of solar magnetic field…Axions and the RR Lyrae Period-Luminosity Relation
We investigate the impact of axions on the period-luminosity relation (PLR) of RR Lyrae stars.Companion masses of Gaia DR3 AstroSpectroSB1 binaries: a Bayesian forward-modelling framework
Gaia Data Release 3 (DR3) has substantially expanded the study of unresolved binaries by providing combined astrometric and spectroscopic orbital solutions for a large sample of non-single stars.LATED: Ly$α$-anchored photometric selection of candidate metal-free and extremely metal-poor star formation from the end of reionisation to cosmic noon
Cosmological simulations allow a low-level tail of Population III (Pop III) star formation to persist to $z=2-6$.LATED: JWST integral field spectroscopy of a galaxy caught in chemical infancy at $z=4.8$ behind Abell 2744
When Population III (Pop III) star formation ended remains an open question.CRIMSONS: An Online Tool for Modeling Chemical Enrichment with Stochastic IMF Sampling
Chemical enrichment is a universal process shaped by several interconnected factors, including stellar feedback, the nature of chemical polluters, and the underlying distribution of stellar masses.The oldest low-$α$ thin disc stars
The formation pathway of the $α$-poor Milky Way thin disc remains under debate.Using Machine Learning to Model Stellar Collisions in our Galactic Center
Direct collisions in the inner pc of the Galactic center can alter the orbits and properties of stars.Physics-Informed Neural Networks for Fast Multilayer Spectral Inversion of Hα 6562.8 A and Ca II 8542.1 A Spectra
Strong chromospheric absorption lines such as H$α$ 6562.8 A and Ca II 8542.1 A provide vital diagnostics of plasma dynamics and thermal structure in the solar chromosphere.
