Gravity as a portal to reheating, leptogenesis and dark matter

open access: yesJournal of High Energy Physics, 2022
We show that a minimal scenario, utilizing only the graviton as an intermediate messenger between the inflaton, the dark sector and the Standard Model (SM), is able to generate simultaneously the observed relic density of dark matter (DM), the baryon ...

The minimal cosmological standard model

open access: yesNuclear Physics B
We propose a novel minimal scenario which simultaneously addresses the following theoretical/cosmological/phenomenological puzzles: (i) the origin of scales, (ii) primordial inflation, (iii) matter-antimatter asymmetry, (iv) tiny neutrino masses, (v ...

That Raw and Ancient Cold: On Graham Harman’s Recasting of Archaeology

open access: yesOpen Philosophy, 2021
This is a comment to Graham Harman’s 2019 response to an article by Þóra Pétursdóttir and Bjørnar Olsen (2018) in which they propose that a materially grounded, archaeological perspective might complement Harman’s historical approach in Immaterialism ...

ORGANIC CARBON CONTENT IN AN ARGIC FAEOZIOM SOIL FROM COJOCNA

open access: yesAgricultura, 2016
Organic matter in the soil is a carbon-rich material that includes plants, animals and microbial residues in various stages of decomposition. Living organisms in the soil and plant roots are part of the carbon reserve in the soil, but are not considered

Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]

open access: yesEPJ Web of Conferences
Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.

Dark fermions and spontaneous CP violation in SU(2)-axion inflation

open access: yesJournal of High Energy Physics, 2020
Remarkably, if CP was spontaneously broken in the physics of inflation, fermions would notice and remember it. Based on that, we present a new (non-thermal) mechanism for generating self-interacting dark Dirac fermions prior to the Hot Big Bang.

Characteristics and sedimentary environment of organic-rich shale in the second member of Paleogene Funing Formation, Subei Basin

open access: yesShiyou shiyan dizhi, 2020
Two sets of organic-rich shales are developed in the second member of Funing Formation (E1f2) in the Subei Basin, which are E1f2shale 1 and E1f2shale 2. They are widely distributed, with rich shows and favorable shale oil conditions.

The ACT bridge census: A search for hot gas between massive galaxy clusters with pair stacking [PDF]

open access: yesEPJ Web of Conferences
Baryonic matter only accounts for 5% of the mass-energy density of our universe, where the other 95% is shared between dark energy and dark matter. Measurements of the early universe predict a certain baryon fraction, that is not detected in the later ...

Model-dependent Galactic Environment Effects on Multitransonic Accretion and Emergent Acoustic Gravity around Kerr Black Holes

open access: yesThe Astrophysical Journal
The hydrodynamics of low-angular-momentum, multitransonic, axisymmetric, inviscid accretion flow onto a rotating black hole in presence of a galactic environment has been systematically investigated in detail using three standard disk geometries and two ...

Figuring Out Gas and Galaxies in Enzo (FOGGIE). IX. The Angular Momentum Evolution of Milky Way–like Galaxies and Their Circumgalactic Gas

open access: yesThe Astrophysical Journal
We investigate the coevolution of the angular momentum of Milky Way–like galaxies, their circumgalactic gas, and their dark matter halos using zoom-in simulations from the Figuring Out Gas and Galaxies in Enzo suite.
