Effect of ionizing photon escape fraction in faint galaxies on modeling reionization history of the universe
Zewei Wu, Andrey Kravtsov, Harley Katz
We present model calculations of the reionization history of hydrogen using star formation histories, computed with a galaxy formation model which reproduces properties of local dw…
On the connection between nitrogen-enhanced field stars and the Galactic globular clusters
Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6
As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…
Updated bounds on ultra-light dark matter from the tiniest galaxies
Simon May, Neal Dalal, Andrey Kravtsov
The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to . This constraint, which excl…
Bursting at the seams: the star-forming main sequence and its scatter at z=3-9 using NIRCam photometry from JADES
C. Simmonds, S. Tacchella, W. McClymont +24
We present a comprehensive study of the star-forming main sequence (SFMS) and its scatter at redshifts , using NIRCam photometry from the JADES survey in the GOODS…
Connecting JWST discovered N/O-enhanced galaxies to globular clusters: Evidence from chemical imprints
Xihan Ji, Vasily Belokurov, Roberto Maiolino +5
Recent JWST observations have revealed a growing population of galaxies at with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to sup…
The realm of Aurora. Density distribution of metal-poor giants in the heart of the Galaxy
Evgeny P. Kurbatov, Vasily Belokurov, Sergey Koposov +11
The innermost portions of the Milky Way's stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted vi…
Blind source separation of the stellar halo
Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov +4
The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and \textit{in-situ} evolution, that form an interweaving tapestry in kinemati…
Constraints on blue and red tilted primordial power spectra using dwarf galaxy properties
Ariane Dekker, Andrey Kravtsov
Although the standard +Cold Dark Matter (CDM) model is well tested on large scales, the primordial power spectrum may deviate from the CDM spectrum on small scales due to…
On the dark matter content of ultra-diffuse galaxies
Andrey Kravtsov
I compare the dark matter content within stellar half-mass radius expected in a CDM-based galaxy formation model with existing observational estimates for the observed dwarf sat…
Stochastic star formation and the abundance of UV-bright galaxies
Andrey Kravtsov, Vasily Belokurov
We use a well-motivated galaxy formation framework to predict stellar masses, star formation rates (SFR), and ultraviolet (UV) luminosities of galaxy populations at redshifts $z\in…
On the contribution of dwarf galaxies to reionization of the Universe
Zewei Wu, Andrey Kravtsov
We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from to at redshifts $…
Modelling Stochastic Star Formation History of Dwarf Galaxies in GRUMPY
Yue Pan, Andrey Kravtsov
We investigate the impact of bursty star formation on several galaxy scaling relations of dwarf galaxies using the galaxy formation model. While this model reprod…
In-situ vs accreted Milky Way globular clusters: a new classification method and implications for cluster formation
Vasily Belokurov, Andrey Kravtsov
We present a new scheme for the classification of the in-situ and accreted globular clusters (GCs). The scheme uses total energy and -component of the orbital angular moment…
Taking the Milky Way for a spin: disc formation in the ARTEMIS simulations
Adam M. Dillamore, Vasily Belokurov, Andrey Kravtsov +1
We investigate the formation (spin-up) of galactic discs in the ARTEMIS simulations of Milky Way-mass galaxies. In almost all galaxies discs spin up at higher [Fe/H] than the Milky…
Baryon Content of Massive Galaxy Clusters at z=0-0.6
Yen-Ting Lin, S. Adam Stanford, Peter R. M. Eisenhardt +3
We study the relationship between two major baryonic components in galaxy clusters, namely the stars in galaxies, and the ionized gas in the intracluster medium (ICM), using 94 clu…
