Powerful Radio-loud Quasars Are Triggered by Galaxy Mergers in the Cosmic Bright Ages

The Astrophysical Journal
While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) driving the onset of fueling and ignition in these active galactic nuclei (AGN)

LGBTQ+ Affirmative Care Training in Counselor Education: A Community‐Based Inquiry

Counselor Education and Supervision, EarlyView.
ABSTRACT Counselor educators, counselors‐in‐training, and LGBTQ+ community members engaged in a community‐based qualitative inquiry exploring LGBTQ+ affirmative care education. Findings revealed counselor educators’ components and delivery of content, developmental implications for applying LGBTQ+ affirmative care, and gaps between education and LGBTQ+

A Physically Motivated Framework to Compare the Merger Timescales of Isolated Low- and High-mass Galaxy Pairs Across Cosmic Time

The Astrophysical Journal
The merger timescales of isolated low-mass pairs (10 ^8 < M _* < 5 × 10 ^9 M _⊙ ) on cosmologically motivated orbits have not yet been studied in detail, though isolated high-mass pairs (5 × 10 ^9 < M _* < 10 ^11 M _⊙ ) have been studied extensively.

Massive Black Hole Binaries from the TNG50-3 Simulation. II. Using Dual AGNs to Predict the Rate of Black Hole Mergers

The Astrophysical Journal, 2023
Dual active galaxy nuclei (dAGNs) trace the population of post-merger galaxies and are the precursors to massive black hole (MBH) mergers, an important source of gravitational waves that may be observed by the Laser Interferometer Space Antenna (LISA ...

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Counter-orbiting tidal debris as the origin of the MW DoS

EPJ Web of Conferences, 2012
The Milky Way satellite galaxies show a phase-space distribution that is not expected from the standard scenario of galaxy formation. This is a strong hint at them being of tidal origin, which would naturally explain their spacial distribution in a disc ...

A New Dissociative Galaxy Cluster Merger: RM J150822.0+575515.2

The Astrophysical Journal
Galaxy cluster mergers that exhibit clear dissociation between their dark matter, intracluster gas, and stellar components are great laboratories for probing dark matter properties.

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, EarlyView.
What's New? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.
