Cosmological smoothed particle hydrodynamics simulations: a hybrid multiphase model for star formation [PDF]
, 2002 We present a model for star formation and supernova feedback that describes the multiphase structure of star-forming gas on scales that are typically not resolved in cosmological simulations.

The cosmological analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 The Effective Field Theory of Large-Scale Structure is a formalism that allows us to predict the clustering of Cosmological Large-Scale Structure in the mildly non-linear regime in an accurate and reliable way.

New Journal of Physics, 2004 The current status of neutrino cosmology is reviewed, from the question of neutrino decoupling and the presence of sterile neutrinos to the effects of neutrinos on the cosmic microwave background and large scale structure. Particular emphasis is put on cosmological neutrino mass measurements.

Exploring bouncing cosmologies with cosmological surveys [PDF]
Science China Physics, Mechanics & Astronomy, 2014 In light of the recent observational data coming from the sky we have two significant directions in the field of theoretical cosmology recently. First, we are now able to make use of present observations, such as the Planck and BICEP2 data, to examine theoretical predictions from the standard inflationary $Λ$CDM which were made decades of years ago ...

Astronomische Nachrichten, EarlyView.ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Journal of High Energy PhysicsGravitational-wave (GW) signals offer a unique window into the dynamics of the early universe. GWs may be generated by the topological defects produced in the early universe, which contain information on the symmetry of UV physics.

Journal of High Energy Physics, 2018 Macroscopic nuggets of quark matter were proposed several decades ago as a candidate for dark matter. The formation of these objects in the early universe requires the QCD phase transition to be first order — a requirement that is not satisfied in the ...

Environmental Policy and Governance, EarlyView.ABSTRACT Thailand has announced ambitious plans to reduce greenhouse gas emissions, including a programme that allows private companies to earn carbon credits from protecting and restoring mangroves. In 2023, the Department of Marine and Coastal Resources (DMCR) began enrolling local communities and private firms in this scheme.

Scientific ReportsIn this article, we explicitly construct the coordinates associated with the Penrose diagram in spacetimes connected via a spacelike thin shell in the following two examples: the generalized black-to-white hole bounce with mass difference and the ...

Thermodynamics of Bardeen black holes in restricted phase space
Physics Letters BIn this paper, we investigate the thermodynamics of Bardeen black holes within the framework of Restricted Phase Space (RPS) thermodynamics. Building upon the holographic interpretation of black hole thermodynamics, we derive key thermodynamic quantities,
