Hyperion: The origin of the stars A far-UV space telescope for high-resolution spectroscopy over wide fields
Erika Hamden, David Schiminovich, Shouleh Nikzad +30
We present Hyperion, a mission concept recently proposed to the December 2021 NASA Medium Explorer announcement of opportunity. Hyperion explores the formation and destruction of m…
Can pre-supernova winds from massive stars enrich the interstellar medium with nitrogen at high redshift?
Arpita Roy, Mark R. Krumholz, Michael A. Dopita +3
Understanding the nucleosynthetic origin of nitrogen and the evolution of the N/O ratio in the interstellar medium is crucial for a comprehensive picture of galaxy chemical evoluti…
CONGRuENTS (COsmic-ray, Neutrino, Gamma-ray and Radio Non-Thermal Spectra). I. A predictive model for galactic non-thermal emission
Matt A. Roth, Mark R. Krumholz, Roland M. Crocker +1
The total luminosity and spectral shape of the non-thermal emission produced by cosmic rays depends on their interstellar environment, a dependence that gives rise to correlations…
The impact of carbon and oxygen abundances on the metal-poor initial mass function
Piyush Sharda, Anish M. Amarsi, Kathryn Grasha +5
Star formation models predict that the metal-poor initial mass function (IMF) can be substantially different from that observed in the metal-rich Milky Way. This changeover occurs…
The cosmic ray ionisation and -ray budgets of star-forming galaxies
Mark R. Krumholz, Roland M. Crocker, Stella S. R. Offner
Cosmic rays in star-forming galaxies are a dominant source of both diffuse -ray emission and ionisation in gas too deeply shielded for photons to penetrate. Though the cosmic ra…
Outflows Driven by Direct and Reprocessed Radiation Pressure in Massive Star Clusters
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz
We use three-dimensional radiation hydrodynamic (RHD) simulations to study the formation of massive star clusters under the combined effects of direct ultraviolet (UV) and dust-rep…
