Journal of Astronomical Telescopes, Instruments, and Systems, 2021 The Galaxy Evolution Probe (GEP) is a concept for a mid- and far-infrared space observatory to measure key properties of large samples of galaxies with large and unbiased surveys. GEP will attempt to achieve zodiacal light and Galactic dust emission photon background-limited observations by utilizing a 6 Kelvin, 2.0 meter primary mirror and sensitive ...

Simulating Galaxy Evolution [PDF]
The 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1998 The forwards approach to galaxy formation and evolution is extremely powerful but leaves several questions unanswered. Foremost among these is the origin of disks.

Galaxy peculiar velocities and evolution-bias [PDF]
, 2007 Galaxy bias can be split into two components: a formation-bias based on the locations of galaxy creation, and an evolution-bias that details their subsequent evolution. In this letter we consider evolution-bias in the peaks model. In this model, galaxy formation takes place at local maxima in the density field, and we analyse the subsequent peculiar ...

Galaxy-galaxy(-galaxy) lensing as a sensitive probe of galaxy evolution [PDF]
2012A&A...547A..77S, 2012 The gravitational lensing effect provides various ways to study the mass environment of galaxies. We investigate how galaxy-galaxy(-galaxy) lensing can be used to test models of galaxy formation and evolution. We consider two semi-analytic galaxy formation models based on the Millennium Run N-body simulation: the Durham model by Bower et al. (2006) and

Secular evolution in galaxies [PDF]
Symposium - International Astronomical Union, 1985 We have adapted the N-body code of Van Albada (1982) to study the secular evolution of a hot collisionless stellar component (E galaxy or galactic bulge) due to slow changes in another component of the same galaxy. Our equilibrium starting model is a non-rotating triaxial ellipsoid with axial ratios 1.3:1.4:2.0; the effects of the “other component” are

A Simple Technique for Predicting High-Redshift Galaxy Evolution [PDF]
, 2015 We show that the ratio of galaxies' specific star formation rates (SSFRs) to their host halos' specific mass accretion rates (SMARs) strongly constrains how the galaxies' stellar masses, specific star formation rates, and host halo masses evolve over ...

The evolution of galaxy formation [PDF]
Astronomy & Geophysics, 2011 Our history of understanding galaxy formation could be traced through the development of individual ideas. A cynic might be tempted to suggest that new catchphrases are developed at a faster rate than genuine progress is made.Comment: 10 pages, Plain TeX,

The evolution of the galaxy UV luminosity function at redshifts z ≃ 8 – 15 from deep JWST and ground-based near-infrared imaging [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We reduce and analyse the available JWST ERO and ERS NIRCam imaging (SMACS0723, GLASS, CEERS) in combination with the latest deep ground-based near-infrared imaging in the COSMOS field (provided by UltraVISTA DR5) to produce a new measurement of the ...

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution [PDF]
Universe, 2022 Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do
