The Origin of Low-redshift Event Rate Excess as Revealed by the Low-luminosity Gamma-Ray Bursts
The Astrophysical Journal, 2023 The relation between the event rate of long gamma-ray bursts and the star formation rate is still controversial, especially at the low-redshift end. Dong et al.

Impact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function [PDF]
Astronomy & Astrophysics, 2018 The stellar initial mass function (IMF) is commonly assumed to be an invariant probability density distribution function of initial stellar masses. These initial stellar masses are generally represented by the canonical IMF, which is defined as the ...

The cosmic merger rate density of compact objects: impact of star formation, metallicity, initial mass function, and binary evolution [PDF]
, 2020 We evaluate the redshift distribution of binary black hole (BBH), black hole - neutron star binary (BHNS) and binary neutron star (BNS) mergers, exploring the main sources of uncertainty: star formation rate (SFR) density, metallicity evolution, common ...

Simulations of magnetized multiphase galactic disk regulated by supernovae explosions [PDF]
, 2014 What exactly controls star formation in the Galaxy remains controversial. In particular, the role of feedback and magnetic field are still partially understood.

ANALYTICAL STAR FORMATION RATE FROM GRAVOTURBULENT FRAGMENTATION [PDF]
The Astrophysical Journal, 2011 We present an analytical determination of the star formation rate (SFR) in molecular clouds, based on a time-dependent extension of our analytical theory of the stellar initial mass function (IMF). The theory yields SFR's in good agreement with observations, suggesting that turbulence {\it is} the dominant, initial process responsible for star ...

DETERMINING STAR FORMATION RATES FOR INFRARED GALAXIES [PDF]
The Astrophysical Journal, 2009 Accepted by ApJ. Revised in proof to strengthen caveats about the extrapolation of these IR templates above L(TIR)>2e12, without suitable local purely starforming template galaxies above this luminosity. Source includes two machine-readable tables of template spectra SEDs, or download the tables from http://mingus.as.arizona.edu/~bjw/ir_templates/

ATLASGAL - star forming efficiencies and the Galactic star formation rate
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The ATLASGAL survey has characterized the properties of approximately 1000 embedded H ii regions and found an empirical relationship between the clump mass and bolometric luminosity that covers 3–4 orders of magnitude. Comparing this relation with simulated clusters drawn from an initial mass function and using different star ...

LOFAR/H-ATLAS: the low-frequency radio luminosity-star formation rate relation [PDF]
, 2018 Radio emission is a key indicator of star formation activity in galaxies, but the radio luminosity–star formation relation has to date been studied almost exclusively at frequencies of 1.4 GHz or above.

Stacked Star Formation Rate Profiles of Bursty Galaxies Exhibit “Coherent” Star Formation [PDF]
The Astrophysical Journal Letters, 2017 Abstract In a recent work based on 3200 stacked Hα maps of galaxies at , Nelson et al. find evidence for “coherent star formation”: the stacked star formation rate (SFR) profiles of galaxies above (below) the “star formation main sequence” (MS) are above (below) that of ...
