SDSS-IV MaNGA: Spatial Evolution of Gas-phase Metallicity Changes Induced by Galaxy Interactions

The Astrophysical Journal
Gas-phase metallicity in interacting and merging galaxies offers key insights into their star formation processes and evolutionary histories. This study investigates the spatial evolution of gas-phase metallicity (i.e., oxygen abundance, 12 + log(O/H ...

Star Formation Properties in Barred Galaxies(SFB). I. Ultraviolet-to-Infrared Imaging and Spectroscopic Studies of NGC 7479

, 2011
Large-scale bars and minor mergers are important drivers for the secular evolution of galaxies. Based on ground-based optical images and spectra as well as ultraviolet data from the Galaxy Evolution Explorer and infrared data from the Spitzer Space ...

Quality of life in heart failure. The heart of the matter. A scientific statement of the Heart Failure Association and the European Association of Preventive Cardiology of the European Society of Cardiology

European Journal of Heart Failure, EarlyView.
For most patients with chronic, progressive illnesses, maintaining good quality of life (QoL), with preserved functional capacity, is just as crucial as prolonging survival. Patients with heart failure (HF) experience much worse QoL and effort intolerance than both the general population and people with other chronic conditions, since they present a ...

Characteristics of pulsed electric field cardiac ablation porcine treatment zones with a focal catheter

Journal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 99-107, January 2023., 2023
Abstract Objectives Pulsed electric field (PEF) therapies employ punctuated energy delivery to kill cells in a volume of tissue through mechanisms that are not dependent on thermal processes. A key component to successful cardiac ablation procedures is ensuring the generation of transmural, contiguous ablation zones, which requires in‐depth knowledge ...

Massive Black Hole Binaries: Dynamical Evolution and Observational Signatures

Advances in Astronomy, 2012
The study of the dynamical evolution of massive black hole pairs in mergers is crucial in the context of a hierarchical galaxy formation scenario. The timescales for the formation and the coalescence of black hole binaries are still poorly constrained ...

Dissecting Halo Components in IFU Data

Galaxies, 2017
While most astronomers are now familiar with tools to decompose images into multiple components such as disks, bulges, and halos, the equivalent techniques for spectral data cubes are still in their infancy.

The evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8

, 2008
We present recent results on the evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8. Results are based on the ESO Distant Cluster Survey (EDisCS) - an ESO large programme aimed at the study of ...

Overmerging and M/L ratios in phenomenological galaxy formation models

, 1999
We show that the discrepancy between the Tully-Fisher relation and the luminosity function predicted by most phenomenological galaxy formation models is mainly due to overmerging of galaxy haloes.

Allobaculum plays a predominant role in the activation of brown fat tissue by diallyl trisulfide

Food Frontiers, EarlyView.
Diallyl trisulfide activates brown adipose tissue and prevents obesity by promoting the relative abundance of Allobaculum in the gut of mice. Oral supplementation of Allobaculum stercoricanis, a primary species in Allobaculum, activates brown adipose tissue and prevents obesity.
