The Mira-Titan Universe. III. Emulation of the Halo Mass Function [PDF]
Astrophysical Journal, 2020 We construct an emulator for the halo mass function over group and cluster mass scales for a range of cosmologies, including the effects of dynamical dark energy and massive neutrinos.

Subhalo mass function and ultralight bosonic dark matter [PDF]
, 2020 Warm dark matter has recently become increasingly constrained by observational inferences about the low-mass end of the subhalo mass function, which would be suppressed by dark matter free streaming in the early Universe.

A Discontinuity in the Low‐Mass Initial Mass Function [PDF]
The Astrophysical Journal, 2007 The origin of brown dwarfs (BDs) is still an unsolved mystery. While the standard model describes the formation of BDs and stars in a similar way recent data on the multiplicity properties of stars and BDs show them to have different binary distribution functions.

Warm dark matter chills out: constraints on the halo mass function and the free-streaming length of dark matter with eight quadruple-image strong gravitational lenses [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The free-streaming length of dark matter depends on fundamental dark matter physics, and determines the abundance and concentration of dark matter haloes on sub-galactic scales.

On the primordial black hole mass function for broad spectra [PDF]
, 2020 We elaborate on the mass function of primordial black holes in the case in which the power spectrum of the curvature perturbation is broad. For the case of a broad and flat spectrum, we argue that such a mass function is peaked at the smallest primordial

Understanding the Fundamental Plane and the Tully Fisher Relation
Frontiers in Astronomy and Space Sciences, 2020 The relation between early type galaxy size, surface brightness and velocity dispersion, “the fundamental plane,” has long been understood as resulting from equilibrium in their largely pressure supported stellar dynamics.

A New Census of the 0.2 < z < 3.0 Universe. I. The Stellar Mass Function [PDF]
Astrophysical Journal, 2019 There has been a long-standing factor-of-two tension between the observed star formation rate density and the observed stellar mass buildup after z ∼ 2.

The Role of Magnetic Fields in Setting the Star Formation Rate and the Initial Mass Function [PDF]
Frontiers in Astronomy and Space Sciences, 2019 Star-forming gas clouds are strongly magnetized, and their ionization fractions are high enough to place them close to the regime of ideal magnetohydrodyamics on all but the smallest size scales.

Toward a Halo Mass Function for Precision Cosmology: The Limits of Universality [PDF]
, 2008 We measure the mass function of dark matter halos in a large set of collisionless cosmological simulations of flat ΛCDM cosmology and investigate its evolution at z≲ 2.
