The evolution of CNO elements in galaxies [PDF]
The Astronomy and Astrophysics Review, 2022 After hydrogen and helium, oxygen, carbon, and nitrogen—hereinafter, the CNO elements—are the most abundant species in the universe. They are observed in all kinds of astrophysical environments, from the smallest to the largest scales, and are at the ...

Inferring the astrophysics of reionization and cosmic dawn from galaxy luminosity functions and the 21-cm signal [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The properties of the first galaxies, expected to drive the Cosmic Dawn (CD) and the Epoch of Reionization (EoR), are encoded in the 3D structure of the cosmic 21-cm signal.

Tales within Tales and Cutoffs within Cutoffs: What Sets the Mass Scale for Galaxies? [PDF]
, 2001 Please answer ``yes'' or ``no'': 1. Does the mass function for clusters of galaxies cut off exponentially? 2. Does the luminosity function for galaxies cut off exponentially? 3. Is the dependence of virial velocity on galaxy luminosity a power law?

The Faintest Dwarf Galaxies [PDF]
Annual Review of Astronomy and Astrophysics, 2019 The lowest luminosity ([Formula: see text] L[Formula: see text]) Milky Way satellite galaxies represent the extreme lower limit of the galaxy luminosity function.

Spiral galaxies with large optical warps [PDF]
, 1999 As a result of our statistical study of 540 edge-on galaxies, we present here the images and preliminary statistical analysis of a sub-sample of 60 galaxies, that were selected to be S-type warped spirals.

The Connection Between Galaxies and Their Dark Matter Halos [PDF]
Annual Review of Astronomy and Astrophysics, 2018 In our modern understanding of galaxy formation, every galaxy forms within a dark matter halo. The formation and growth of galaxies over time is connected to the growth of the halos in which they form.

ASSESSING ASTROPHYSICAL UNCERTAINTIES IN DIRECT DETECTION WITH GALAXY SIMULATIONS [PDF]
The Astrophysical Journal, 2016 ABSTRACT We study the local dark matter velocity distribution in simulated Milky Way-mass galaxies, generated at high resolution with both dark matter and baryons. We find that the dark matter in the solar neighborhood is influenced appreciably by the inclusion of baryons, increasing the speed of dark matter particles compared to dark ...

Photometric and kinematical study of nearby groups of galaxies around IC 65 and NGC 6962 [PDF]
, 2006 We discuss the structure, galaxy content and kinematics of a sparse, probably collapsing group around IC 65 and an evolved rich group around NGC 6962Comment: Poster contribution on 2 pages with 2 figures to be published in ESO Astrophysics Symposia ...

Cold fronts: probes of plasma astrophysics in galaxy clusters [PDF]
Journal of Plasma Physics, 2016 The most massive baryonic component of galaxy clusters is the ‘intracluster medium’ (ICM), a diffuse, hot, weakly magnetized plasma that is most easily observed in the X-ray band. Despite being observed for decades, the macroscopic transport properties of the ICM are still not well constrained.

Cosmology and Astrophysics with Standard Sirens and Galaxy Catalogs in View of Future Gravitational Wave Observations [PDF]
Astrophysical Journal, 2023 With the growing number of gravitational wave (GW) detections and the advent of large galaxy redshift surveys, a new era in cosmology is emerging. This study explores the synergies between GWs and galaxy surveys to jointly constrain cosmological and GW ...
