Evolution of Interstellar Clouds in Local Group Dwarf Spheroidal Galaxies in the Context of Their Star Formation Histories [PDF]

open access: yes, 1999
We consider evolution of interstellar clouds in Local Group dwarf spheroidal galaxies (dSphs) in the context of their observed star formation histories.

Calibration of star formation rate tracers for short- and long-lived star formation episodes [PDF]

open access: yes, 2009
To derive the history of star formation in the Universe a set of calibrated star formation rate tracers at different wavelengths is required. The calibration has to consistently take into account the effects of extinction, star formation regime (short or

Radio Triggered Star Formation in Cooling Flows [PDF]

open access: yesNew Astron.Rev. 46 (2002) 141-148, 1999
The giant galaxies located at the centers of cluster cooling flows are frequently sites of vigorous star formation. In some instances, star formation appears to have been triggered by the galaxy's radio source.

Star Formation during Galaxy Formation [PDF]

open access: yes, 2011
Young galaxies are clumpy, gas-rich, and highly turbulent. Star formation appears to occur by gravitational instabilities in galactic disks. The high dispersion makes the clumps massive and the disks thick. The star formation rate should be comparable to

The star formation history of the Large Magellanic Cloud as seen by star clusters and stars [PDF]

open access: yes, 2010
The aim of this work is to test to what extent the star cluster population of a galaxy can be utilised to constrain or estimate the star formation history, with the Large Magellanic Cloud as our testbed. We follow two methods to extract information about

Direct Detections of Young Stars in Nearby Elliptical Galaxies [PDF]

open access: yes, 2013
Small amounts of star formation in elliptical galaxies are suggested by several results: surprisingly young ages from optical line indices, cooling X-ray gas, and mid-IR dust emission. Such star formation has previously been difficult to directly detect,

A Comprehensive Study of Galaxies at z ∼ 9–16 Found in the Early JWST Data: Ultraviolet Luminosity Functions and Cosmic Star Formation History at the Pre-reionization Epoch [PDF]

open access: yesAstrophysical Journal Supplement Series, 2022
We conduct a comprehensive study on dropout galaxy candidates at z ∼ 9–16 using the first 90 arcmin2 James Webb Space Telescope (JWST) Near Infrared Camera images taken by the early release observations (ERO) and early release science programs.

The Evolution of the IR Luminosity Function and Dust-obscured Star Formation over the Past 13 Billion Years [PDF]

open access: yesAstrophysical Journal, 2021
We present the first results from the Mapping Obscuration to Reionization with ALMA (MORA) survey, the largest Atacama Large Millimeter/submillimeter Array (ALMA) blank-field contiguous survey to date (184 arcmin2) and the only at 2 mm to search for ...

A compendium of distances to molecular clouds in the Star Formation Handbook [PDF]

open access: yesAstronomy & Astrophysics, 2020
Accurate distances to local molecular clouds are critical for understanding the star and planet formation process, yet distance measurements are often obtained inhomogeneously on a cloud-by-cloud basis.

Impact Induced Oxidation and Its Implications for Early Mars Climate

open access: yesGeophysical Research Letters, 2023
H2 in a CO2 atmosphere may serve as a potential solution to the early Mars climate paradox, but its unknown sources cast doubts on the proposed mechanism. Impact cratering is an energetic process that may modify the surface redox budget.
