The z = 9.625 Cosmic Gems galaxy was a compact “blue monster” propelled by massive star clusters★

Astronomy & Astrophysics
The recent discovery of five massive stellar clusters at z = 9.625 in the Cosmic Gems galaxy has raised the question about the formation mechanism of star clusters in the first 500 Myr after the Big Bang. We inferred the total stellar mass in clusters by

Mass Transfer by Stellar Wind

, 2014
I review the process of mass transfer in a binary system through a stellar wind, with an emphasis on systems containing a red giant. I show how wind accretion in a binary system is different from the usually assumed Bondi-Hoyle approximation, first as ...

A Census of Star Formation Histories of Massive Galaxies at 0.6 < z < 1 from Spectrophotometric Modeling Using Bagpipes and Prospector

The Astrophysical Journal
We present individual star formation histories (SFHs) of ∼3000 massive galaxies (log( M _* / M _⊙ ) > 10.5) from the Large Early Galaxy Astrophysics Census spectroscopic survey at a lookback time of ∼7 billion yr and quantify the population trends ...

Supernovae and Stellar Mass Loss [PDF]

Highlights of Astronomy, 1986
AbstractType I supernovae can be modeled as the carbon deflagration of white dwarfs and Type II supernovae as the explosions of massive stars with hydrogen envelopes. The massive stars at the ends of their lives are expected to be red supergiants, which are observed to have slow, dense winds.

Coevolution of Nuclear Star Clusters and Massive Black Holes: Extreme-mass-ratio Inspirals

The Astrophysical Journal
We explore extreme-mass-ratio inspirals (EMRIs) in the coevolution of massive black holes (MBHs) and nuclear star clusters (NSCs), which host diverse stellar populations across a wide range of masses. The dynamics are simulated self-consistently with GNC

The stellar initial mass function [PDF]

Proceedings of the International Astronomical Union, 2006
Abstract The IMF UNIVERSALITY HYPOTHESIS cannot be discarded despite the existence of the CLUSTER IMF THEOREM. This means that the currently existing star-formation theory fails to describe the stellar outcome. The IGIMF THEOREM, however, predicts a variation of galaxy-wide IMFs in dependence of the galaxy's star-formation rate even if the IMF ...

An Early Dark Matter–dominated Phase in the Assembly History of Milky Way–mass Galaxies Suggested by the TNG50 Simulation and JWST Observations

The Astrophysical Journal Letters
Whereas well-studied galaxies at cosmic noon are found to be baryon dominated within the effective radius, recent JWST observations of z ∼ 6–7 galaxies with stellar masses of only M _* ∼ 10 ^8−9 M _⊙ surprisingly indicate that they are dark matter ...

The SL2S Galaxy-scale Lens Sample. V. Dark Matter Halos and Stellar IMF of Massive Early-type Galaxies out to Redshift 0.8

, 2014
We investigate the cosmic evolution of the internal structure of massive early-type galaxies over half of the age of the Universe. We perform a joint lensing and stellar dynamics analysis of a sample of 81 strong lenses from the SL2S and SLACS surveys ...
