FLAMINGO: calibrating large cosmological hydrodynamical simulations with machine learning [0.03%]

To fully take advantage of the data provided by large-scale structure surveys, we need to quantify the potential impact of baryonic effects, such as feedback from active galactic nuclei (AGN) and star formation, on cosmological observables....
Pushing the limits of detectability: mixed dark matter from strong gravitational lenses [0.03%]
探测的极限:强引力透镜下的混合暗物质

One of the frontiers for advancing what is known about dark matter lies in using strong gravitational lenses to characterize the population of the smallest dark matter haloes. There is a large volume of information in strong gravitational l...

Cosmic rays in star-forming galaxies are a dominant source of both diffuse γ-ray emission and ionization in gas too deeply shielded for photons to penetrate. Though the cosmic rays responsible for γ-rays and ionization are of different en...
Common envelope binary interaction simulations between a thermally pulsating AGB star and a low mass companion [0.03%]
热脉冲Asymptotic Giant Branch(AGB)恒星与其低质量伴星相互作用的包层共存二元系统模拟

At least one in five of all planetary nebulae are the product of a common envelope (CE) interaction, where the companion in-spirals into the envelope of an asymptotic giant branch (AGB) star ejecting the nebula and leaving behind a compact ...

The latticework structure known as the cosmic web provides a valuable insight into the assembly history of large-scale structures. Despite the variety of methods to identify the cosmic web structures, they mostly rely on the assumption that...

We use a series of magnetohydrodynamic simulations including both radiative and protostellar outflow feedback to study environmental variation of the initial mass function (IMF). The simulations represent a carefully-controlled experiment w...
The role of the hadron-quark phase transition in core-collapse supernovae [0.03%]

Pia Jakobus et al.
The hadron-quark phase transition in quantum chromodynamics has been suggested as an alternative explosion mechanism for core-collapse supernovae. We study the impact of three different hadron-quark equations of state (EoS) with first-order...
Gamma-ray burst data strongly favour the three-parameter fundamental plane (Dainotti) correlation over the two-parameter one [0.03%]
伽玛射线暴数据强烈支持三维基本平面(DAINOTTI)相关性优于二维相关性

Gamma-ray bursts (GRBs), observed to redshift z = 9.4, are potential probes of the largely unexplored z ∼ 2.7-9.4 part of the early Universe. Thus, finding relevant relations among GRB physical properties is crucial. We find that the Plati...
Standardizing Platinum Dainotti-correlated gamma-ray bursts, and using them with standardized Amati-correlated gamma-ray bursts to constrain cosmological model parameters [0.03%]
用标准化的Platinum Dainotti相关γ射线暴和Amati相关γ射线暴限制宇宙学模型参数

We show that the Platinum gamma-ray burst (GRB) data compilation, probing the redshift range 0.553 ≤ z ≤ 5.0, obeys a cosmological-model-independent three-parameter Fundamental Plane (Dainotti) correlation and so is standardizable. While ...

Depending on the stellar densities, protoplanetary discs in stellar clusters undergo: background heating; disc truncation-driven by stellar encounter; and photoevaporation. Disc truncation leads to reduced characteristic sizes and disc mass...
