The Radio Spectral Energy Distribution and Star-formation Rate Calibration in Galaxies [PDF]

open access: bronze, 2017
We study the spectral energy distribution (SED) of the radio continuum (RC) emission from the Key Insight in Nearby Galaxies Emitting in Radio (KINGFISHER) sample of nearby galaxies to understand the energetics and origin of this emission.

The Role of Magnetic Fields in Setting the Star Formation Rate and the Initial Mass Function [PDF]

open access: yesFrontiers 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.

Measuring the star formation rate with gravitational waves from binary black holes [PDF]

open access: yesAstrophysical Journal, 2019
A measurement of the history of cosmic star formation is central to understand the origin and evolution of galaxies. The measurement is extremely challenging using electromagnetic radiation: significant modeling is required to convert luminosity to mass,

Models of Late-type Disk Galaxies: 1-D Versus 2-D

open access: yesOpen Astronomy, 2014
We investigate the effects of stochasticity on the observed galaxy parameters by comparing our stochastic star formation two-dimensional (2-D) galaxy evolution models with the commonly used one-dimensional (1-D) models with smooth star formation. The 2-D

Interpreting the Cosmic Infrared Background: Constraints on the Evolution of the Dust‐enshrouded Star Formation Rate [PDF]

open access: green, 2001
The mid-infrared local luminosity function is evolved with redshift to fit the spectrum of the cosmic infrared background (CIRB) at λ > 5 μm and the galaxy counts from various surveys at mid-infrared, far-infrared, and submillimeter wavelengths.

Black Hole Accretion Correlates with Star Formation Rate and Star Formation Efficiency in Nearby Luminous Type 1 Active Galaxies [PDF]

open access: yes, 2020
We investigate the relationship between black hole accretion and star formation in a sample of 453 z ≈ 0.3 type 1 active galactic nuclei (AGNs).

Star formation rate in Holmberg IX dwarf galaxy [PDF]

open access: yesSerbian Astronomical Journal, 2011
In this paper we use previously determined Hα fluxes for dwarf galaxy Holmberg IX (Arbutina et al. 2009) to calculate star formation rate (SFR) in this galaxy.

Strong dependence of Type Ia supernova standardization on the local specific star formation rate [PDF]

open access: yesAstronomy & Astrophysics, 2018
As part of an on-going effort to identify, understand and correct for astrophysics biases in the standardization of Type Ia supernovae (SN Ia) for cosmology, we have statistically classified a large sample of nearby SNe Ia into those that are located in ...

Revealing the Galaxy–Halo Connection through Machine Learning

open access: yesThe Astrophysical Journal, 2023
Understanding the connections between galaxy stellar mass, star formation rate, and dark matter halo mass represents a key goal of the theory of galaxy formation. Cosmological simulations that include hydrodynamics, physical treatments of star formation,

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly

open access: yesThe Astrophysical Journal, 2023
Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We
