Active Galactic Nucleus Quenching in Simulated Dwarf Galaxies

The Astrophysical Journal, 2023
We examine the quenching characteristics of 328 isolated dwarf galaxies $\left({10}^{8}\lt {M}_{\mathrm{star}}/{M}_{\odot }\lt {10}^{10}\right)$ within the Romulus25 cosmological hydrodynamic simulation.

Growing Massive Black Holes in a Local Group Environment: the Central Supermassive, Slowly Sinking, and Ejected Populations

, 2011
We explore the growth of < 10^7 Msun black holes that reside at the centers of spiral and field dwarf galaxies in a Local Group type of environment. We use merger trees from a cosmological N-body simulation known as Via Lactea II (VL-2) as a framework to

Gut Microbe‐Driven Resistance Mechanisms in Propylea Japonica: Insights from Horizontal Gene Transfer and Oxidative Phosphorylation

Advanced Science, EarlyView.
Acinetobacter regulates dinotefuran tolerance in Propylea japonica by mediating the expression of the horizontally transferred gene PjDUF1. Abstract Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer.

Hubble Space Telescope Imaging of the Active Dwarf Galaxy RGG 118

, 2017
RGG 118 (SDSS 1523+1145) is a nearby ($z=0.0243$), dwarf disk galaxy ($M_{\ast}\approx2\times10^{9} M_{\odot}$) found to host an active $\sim50,000$ solar mass black hole at its core (Baldassare et al. 2015). RGG 118 is one of a growing collective sample

The Insistence of Blackness and the Persistence of Antiblackness in Ireland

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Two-exon skipping within MLPH is associated with coat color dilution in rabbits. [PDF]

PLoS ONE, 2013
Coat color dilution turns black coat color to blue and red color to cream and is a characteristic in many mammalian species. Matings among Netherland Dwarf, Loh, and Lionhead Dwarf rabbits over two generations gave evidence for a monogenic autosomal ...

On Companion-Induced Off-Center Supernova-Like Explosions [PDF]

, 2000
We suggest that a neutron star with a strong magnetic field, spiraling into the envelope of a companion star, can generate a ``companion induced SN-like off-center explosion".

Beyond Robodebt: Media Representations of Welfare and Fraud Before and After the Robodebt Royal Commission

Australian Journal of Social Issues, EarlyView.
ABSTRACT Australia's Robodebt scheme, an automated debt recovery program introduced in 2016, was exposed by the Robodebt Royal Commission (RC) as a serious failure of public administration and source of significant harm for thousands of Australians. Through a critical discourse analysis (CDA) of Australian news media, this study explores whether the RC'
