SDSS. IV. MaNGA: The Impact of the Acquisition of Gas with Opposite Angular Momentum on the Evolution of Galaxies

The Astronomical Journal
A gaseous counterrotating galaxy is a galaxy containing a gas component with opposite angular momentum to the main stellar disk. The counterrotating gas provides direct evidence for the accretion of external material, a key aspect in hierarchical galaxy ...

‘FROM GHETTO TO HABITUS FACTORY’ ROMA CAMPS IN ITALY: An Empirical Extension of Loïc Wacquant's Theorization

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article we apply Wacquant's conceptualization of the ghetto to an analysis of interviews conducted with Roma people living in the state‐enforced camps of Turin, Italy. We illustrate how the elements characterizing a ghetto according to Wacquant (i.e.

A New Framework for Active Galactic Nucleus Accretion and Jet Feedback in Numerical Simulations

The Astrophysical Journal Supplement Series
Accurate modeling of active galactic nucleus (AGN) feedback, especially due to relativistic jets, is crucial for understanding the cool-core problem in galaxy clusters.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

Modeling Dust Production, Growth, and Destruction in Reionization-era Galaxies with the CROC Simulations: Methods and Parameter Exploration

The Astrophysical Journal, 2022
We introduce a model for the explicit evolution of interstellar dust in a cosmological galaxy formation simulation. We post-process a simulation from the Cosmic Reionization on Computers project, integrating an ordinary differential equation for the ...

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

The Growth of Galaxy Stellar Haloes over 0.2 ≤ z ≤ 1.1

The Astrophysical Journal
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar halo buildup probe the processes that drive galaxy size and stellar mass ...

The impact of radio feedback from active galactic nuclei in cosmological simulations: Formation of disk galaxies

, 2007
In this paper, we present a new implementation of feedback due to active galactic nuclei (AGN) in cosmological simulations of galaxy formation. We assume that a fraction of jet energy, which is generated by an AGN, is transferred to the surrounding gas ...
