The Binary Fraction of Milky Way Field Stars in DESI: Dependence on Chemical Abundance
Tian Qiu, Wenting Wang, Sergey E. Koposov +39
Binary populations encode information about the physical conditions of star formation and the subsequent evolution of stellar populations. Adopting a statistical method based on mu…
Planetary Accretion Is Less Frequent in Wide Binaries: Evidence from Metal-Enriched White Dwarfs in DESI DR1
Siyi Xu, Laura. K. Rogers, Joan Najita +32
Binary stars are common in the Galaxy, and understanding how stellar binarity influences the formation and evolution of planetary systems is an active area of research. In this stu…
The DESI Data Release 1 white dwarf catalogue
Andrew Swan, Boris T. Gänsicke, Paula Izquierdo +49
The Dark Energy Spectroscopic Instrument is conducting a redshift survey, mapping the universe in three dimensions to measure the history of cosmic expansion. As well as extragalac…
The IMF package: a toolkit implementing mass functions and statistical tools to analyze them
Theo Richardson, Adam Ginsburg, Sergey Koposov
Mass functions are used in all areas of astrophysics. The stellar initial mass function (IMF), in particular, plays a central role in modeling stellar populations in galaxies. Howe…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
The Binary Fraction of Stars in the Dwarf Galaxy Ursa Minor via Dark Energy Spectroscopic Instrument
Tian Qiu, Wenting Wang, Sergey Koposov +45
We utilize multi-epoch line-of-sight velocity measurements from the Milky Way Survey of the Dark Energy Spectroscopic Instrument to estimate the binary fraction for member stars in…
Constraining the phase shift of relativistic species in DESI BAOs
Abbé M. Whitford, Hugo Rivera-Morales, Cullan Howlett +36
In the early Universe, neutrinos decouple quickly from the primordial plasma and propagate without further interactions. The impact of free-streaming neutrinos is to create a tempo…
