Cloud-cloud collisions triggering star formation in galaxy simulations [PDF]
MNRAS, 527, 10077 (2024), 2023 Cloud-cloud collisions (CCCs) are expected to compress gas and trigger star formation. However, it is not well understood how the collisions and the induced star formation affect galactic-scale properties. By developing an on-the-fly algorithm to identify CCCs at each timestep in a galaxy simulation and a model that relates CCC-triggered star formation

How to Measure Galaxy Star Formation Histories. II. Nonparametric Models [PDF]
Astrophysical Journal, 2018 Nonparametric star formation histories (SFHs) have long promised to be the “gold standard” for galaxy spectral energy distribution (SED) modeling as they are flexible enough to describe the full diversity of SFH shapes, whereas parametric models rule out

HH 80/81: Structure and Kinematics of the Fastest Protostellar Outflow
The Astrophysical Journal, 2023 Hubble Space Telescope (HST) images obtained in 2018 are combined with archival HST data taken in 1995 to detect changes and measure proper motions in the HH 80/81 shock complex, which is powered by the fastest known jet driven by a forming star, the ...

Morphology and star formation in IllustrisTNG: the build-up of spheroids and discs [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Using the IllustrisTNG simulations, we investigate the connection between galaxy morphology and star formation in central galaxies with stellar masses in the range 109–1011.5 M⊙.

THE AVERAGE STAR FORMATION HISTORIES OF GALAXIES IN DARK MATTER HALOS FROM z = 0–8 [PDF]
, 2012 We present a robust method to constrain average galaxy star formation rates (SFRs), star formation histories (SFHs), and the intracluster light (ICL) as a function of halo mass.

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.

Membership Analysis and 3D Kinematics of the Star-forming Complex around Trumpler 37 Using Gaia-DR3
The Astrophysical Journal, 2023 Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are very useful for studying large star-forming complexes.

A Redshift-independent Efficiency Model: Star Formation and Stellar Masses in Dark Matter Halos at z ≳ 4 [PDF]
Astrophysical Journal, 2018 We explore the connection between the UV luminosity functions (LFs) of high-z galaxies and the distribution of stellar masses and star formation histories (SFHs) in their host dark matter halos.
