Identification and properties of intense star-forming galaxies at redshifts z > 10 [PDF]
Nature Astronomy, 2022 The JWST Advanced Deep Extragalactic Survey using NIRCam to find the earliest galaxies reveals the size and star formation rates of four extreme redshift ( z > 10) galaxies of the distant Universe. Surveys with the James Webb Space Telescope (JWST) have

The E-MOSAICS project: simulating the formation and co-evolution of galaxies and their star cluster populations [PDF]
, 2017 We introduce the MOdelling Star cluster population Assembly In Cosmological Simulations within EAGLE (E-MOSAICS) project. E-MOSAICS incorporates models describing the formation, evolution, and disruption of star clusters into the EAGLE galaxy formation ...

Publications of the Astronomical Society of the Pacific, 1996 Current ideas on the formation of the Galaxy are reviewed. Many of the observed characteristics of our Milky Way System are consistent with a scenario in which the Galaxy formed inside out, with the inner part of it evolving by rapid collapse of a single protogalaxy, while the outer halo was accreted over an extended period.

Chemie Ingenieur Technik, EarlyView., 2023 Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

NIHAO - XI. Formation of ultra-diffuse galaxies by outflows [PDF]
, 2016 We address the origin of Ultra-Diffuse Galaxies (UDGs), which have stellar masses typical of dwarf galaxies but effective radii of Milky Way-sized objects. Their formation mechanism, and whether they are failed $\rm L_{\star}$ galaxies or diffuse dwarfs,

The Formation of Galaxies [PDF]
Symposium - International Astronomical Union, 1983 The presently fashionable ideas for galaxy formation are reviewed briefly, and it is concluded that the standard isothermal heirarchy fits the available data best. A simple infall picture is presented which explains many of the observed properties of disk galaxies.

A Model for the Origin of Bursty Star Formation in Galaxies [PDF]
, 2017 We propose a simple analytic model to understand when star formation is time-steady versus bursty in galaxies. Recent models explain the observed Kennicutt-Schmidt relation between star formation rate and gas surface densities in galaxies as resulting ...

Strangulation as the primary mechanism for shutting down star formation in galaxies [PDF]
Nature, 2015 Local galaxies are broadly divided into two main classes, star-forming (gas-rich) and quiescent (passive and gas-poor). The primary mechanism responsible for quenching star formation in galaxies and transforming them into quiescent and passive systems is

The formation of galaxy discs [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 Galaxy disk formation must incorporate the multiphase nature of the interstellar medium. The resulting two-phase structure is generated and maintained by gravitational instability and supernova energy input, which yield a source of turbulent viscosity that is able to effectively compete in the protodisk phase with early angular momentum loss of the ...

The ATLAS3D Project – XXX. Star formation histories and stellar population scaling relations of early-type galaxies [PDF]
, 2015 We present the stellar population content of early-type galaxies from the ATLAS^(3D) survey. Using spectra integrated within apertures covering up to one effective radius, we apply two methods: one based on measuring line-strength indices and applying ...
