Dynamics of Dwarf Galaxies Disfavor Stellar-Mass Black Holes as Dark Matter. [PDF]
Physical Review Letters, 2017 We study the effects of black hole dark matter on the dynamical evolution of stars in dwarf galaxies. We find that mass segregation leads to a depletion of stars in the center of dwarf galaxies and the appearance of a ring in the projected stellar ...

The Astrophysical Journal, 2023 In this empirical work, we aim to quantify the systematic uncertainties in stellar-mass ( M _⋆ ) estimates made from spectral energy distribution (SED) fitting through stellar population synthesis (SPS) for galaxies in the local Universe by using the ...

The stellar mass-halo mass relation of isolated field dwarfs : a critical test of ΛCDM at the edge of galaxy formation [PDF]
, 2016 We fit the rotation curves of isolated dwarf galaxies to directly measure the stellar mass-halo mass relation (M*-M200) over the mass range 5 × 105 ≲ M*/M⊙ ≲ 108.

The Astronomical Journal, 2023 High-precision stellar masses and radii measured directly from binaries can effectively calibrate stellar models. However, such a database containing full spectral types and a large range of metallicity is still not fully established. A continuous effort

Effect of Local Environment and Stellar Mass on Galaxy Quenching and Morphology at 0.5 < z < 2.0 [PDF]
, 2017 We study galactic star formation activity as a function of environment and stellar mass over 0.5 < z < 2.0 using the FourStar Galaxy Evolution (ZFOURGE) survey.

A STEEPER THAN LINEAR DISK MASS–STELLAR MASS SCALING RELATION [PDF]
, 2016 The disk mass is among the most important input parameter for every planet formation model to determine the number and masses of the planets that can form.

The Astrophysical Journal, 2023 Based on independent shear measurements using the Dark Energy Camera Legacy Survey/DR8 imaging data, we measure the weak lensing signals around isolated central galaxies (ICGs) from Sloan Digital Sky Survey/DR7 at z ∼ 0.1.

The dependence of convective core overshooting on stellar mass [PDF]
, 2016 Convective core overshooting extends the main-sequence lifetime of a star. Evolutionary tracks computed with overshooting are quite different from those that use the classical Schwarzschild criterion, which leads to rather different predictions for the ...

Constraining Stellar-mass Black Hole Mergers in AGN Disks Detectable with LIGO [PDF]
Astrophysical Journal, 2017 Black hole (BH) mergers detectable with the Laser Interferometer Gravitational-wave Observatory (LIGO) can occur in active galactic nucleus (AGN) disks.

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors
Population Ecology, EarlyView.Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...
