Overmassive Supermassive Black Holes in SDSS Close Galaxy Pairs

The Astrophysical Journal
Supermassive black holes (SMBHs) and their host galaxies coevolve through channels such as hierarchical merging and active galactic nuclei (AGN) feedback, establishing tight scaling relations between SMBH masses and the properties of the host galaxies ...

PHOTOMETRIC DECOMPOSITION OF MERGERS IN DISK GALAXIES [PDF]

The Astrophysical Journal, 2014
Several observational studies and numerical simulations suggest that mergers must contribute to the evolution of galaxies; however, the role that they play is not yet fully understood. In this paper we study a sample of 52 double nucleus disk galaxies that are considered as candidates for a minor merger event.

Liquid biopsy across cancers: Integrating circulating biomarkers, tumor biology, artificial intelligence, and clinical translation

Interdisciplinary Medicine, EarlyView.
Liquid biopsy uses non‐invasive sampling of blood or body fluids to isolate circulating analytes, including circulating tumor DNA, circulating tumor cells, extracellular vesicles, and RNA. These are analyzed using next‐generation sequencing, qPCR, and proteomics to inform cancer detection, monitoring, and characterization. Figure created with BioRender.

Enhanced Star Formation and Black Hole Accretion Rates in Galaxy Mergers in IllustrisTNG50

The Astrophysical Journal
Many theoretical and observational studies have suggested that galaxy mergers may trigger enhanced star formation or active galactic nucleus activity.

Galaxy pairs as a probe for mergers at z ~ 2 [PDF]

, 2011
In this work I investigate the redshift evolution of pair fraction of a sample of 196 massive galaxies from z = 0 to 3, selected from the COSMOS field. We find that on average a massive galaxy undergoes ~ 1.1 \pm 0.5 major merger since z = 3.

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

HD‐DRUM Rhythmic Training in Huntington's Disease: Feasibility, Motor, and Brain Microstructural Pilot Signals

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Rhythmic cuing may benefit motor functions in Huntington's disease (HD) by compensating for the loss of predictive timing associated with basal ganglia degeneration. To our knowledge no remote rhythmic training application has been developed or evaluated that seeks to improve function in HD.

The Lyα and Continuum Origins Survey. III. Investigating the Link between Galaxy Morphology, Merger Properties, and LyC Escape

The Astrophysical Journal
Characterizing the mechanisms and galaxy properties conducive to the escape of ionizing (LyC) emission is necessary to accurately model the Epoch of Reionization and identify the sources that powered it.

Investigating the role of mergers in galaxy assembly in the early Universe (z > 5)

Astronomy & Astrophysics
Galaxy mergers play a crucial role in shaping the morphology, the star formation, and the mass growth of galaxies across cosmic time. While mergers have been extensively investigated in the local Universe, the evolution of their frequency and physical ...

On the Use of Galaxy Catalogs in Gravitational-wave Parameter Estimation

The Astrophysical Journal
A major challenge in gravitational-wave (GW) multimessenger astrophysics is the imprecise localization of GW compact binary mergers. We investigate the use of a method to include galaxy catalog information in performing parameter estimation of these ...
