We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their...

We study a global transonic solution for a relativistic, magnetized, viscous advective accretion flow around a rotating black hole, incorporating the effects of mass and angular momentum loss through winds. Our model con...

Stellar-mass black holes (BHs) surrounded by neutrino-dominated accretion flows (NDAFs) are a leading central engine of gamma-ray bursts (GRBs). In this work, we investigate the electron fraction distribution in NDAFs wi...

Context. Many low-redshift active galactic nuclei harbor a supermassive black hole accreting matter at low or medium rates. At such rates, the accretion flow usually consists of a cold optically thick disk, plus a hot, l...

Lu-Hf isotope data are presented for dated Permian zircon grains from six samples of the latest Palaeozoic to Jurassic low-grade metasedimentary rocks of western Patagonia and the northern Antarctic Peninsula, as well as...

We develop a simple model for computing planetary formation based on the core instability model for the gas accretion and the oligarchic growth regime for the accretion of the solid core. In this model several planets ca...

With the aim of studying the final mass distribution of extrasolar planets, we have developed a simple model based on the core instability model, which allows us to form a large population of planets and make them evolve...

Aims. The equation of state calculated by Saumon and collaborators has been adopted in most core-accretion simulations of giant-planet formation performed to date. Since some minor errors have been found in their origina...

The analysis of the pre-Andean history of the Central Andes shows a complex tectonic evolution. The basement of the Andean continental margin was formed by the accretion of Precambrian blocks during the formation of Rodi...

Coastal ecosystems such as mangroves, seagrasses, and coral reefs are highly sensitive to shoreline instability and rapid land-use changes in industrializing regions. Nayband Gulf, located adjacent to the Pars Special Ec...

Este experimento foi realizado para estimar a exigência de energia metabolizável (EM) para codornas de corte de 1 a 14 dias de idade. Foram utilizadas 1.140 aves com 1 dia de idade, distribuídas em delineamento inteir...

Nonlinear structure formation for fermionic dark matter particles leads to dark matter density profiles with a degenerate compact core surrounded by a diluted halo. For a given fermion mass, the core has a critical mass ...

JWST has revealed an abundance of low-luminosity active galactic nuclei (AGN) at high redshifts ( z  >  3), pushing the limits of black hole (BH) science in the early Universe. Results have claimed that these BHs are s...

We report an extremely rare X-ray active blue straggler star (BSS) in Collinder 261, undergoing ongoing Roche-lobe overflow in a semidetached binary in an Algol-type configuration with an orbital period of P _orb  ∼ ...

Foram utilizados 12 cordeiros machos, inteiros, com peso médio de 31,6kg. Os cordeiros foram alimentados com dietas à base de milho e farelo de soja, suplementadas com diferentes fontes de cálcio: calcário calcítico...

Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way. In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important probes of an on-going merger. Aims. Our main goal...

We study the evolution of dust in a cosmological volume using a hydrodynamical simulation in which the dust production is coupled with the MUPPI (MUlti Phase Particle Integrator) sub-resolution model of star formation an...

ABSTRACT The objective of this study was to evaluate the effects of combining immunocastration and β-adrenergic agonists (β-AA) on blood metabolites and their correlations with performance and carcass traits of Nellore...

We introduce a numerical optimization method to extract the X-ray reverberation response functions from multiband light curves of active galactic nuclei. This approach does not require prior assumptions about the geometr...

Mineral-associated organic matter, the dominant form of relatively stable carbon (C) in soil, often co-occurs with reactive iron (Fe) and aluminum (Al) phases across soils. Yet, how organo-metallic associations at the mo...

My Khe Beach, Da Nang, Vietnam, has experienced a dramatic transition from accretion (pre-2015) to severe erosion since 2016, with shoreline retreat reaching −42.98 m during the 2024–2025 Northeast (NE) monsoon. Thi...
