Integrated specific star formation rates of galaxies, groups, and clusters: A continuous upper limit with stellar mass? [PDF]

Astron.Astrophys. 451 (2006) L13-L16, 2006
Aims: We investigate the build-up of stellar mass through star formation in field galaxies, galaxy groups, and clusters in order to better understand the physical processes regulating star formation in different haloes. Methods: In order to do so we relate ongoing star formation activity to the stellar mass by studying the integrated specific star ...

Genomic Insights into Post‐Domestication Expansion and Selection of Body Size in Ponies

Advanced Science, EarlyView.
The authors’ research delves into the history of ponies by assembling a pony genome and integrating horse genomes. This unveils genetic connections between Asian and European pony breeds. Cis‐regulatory elements of key genes impacting body size are also identified.

THERMAL AND CHEMICAL EVOLUTIONS OF GALAXY CLUSTERS OBSERVED WITH SUZAKU

Acta Polytechnica, 2013
We studied the properties of the intracluster medium (ICM) of galaxy clusters to outer regions observed with Suzaku. The observed temperature dropped by about ~30% from the central region to the virial radius of the clusters.

Implications of the remarkable homogeneity of galaxy groups and clusters [PDF]

, 2009
We measure the diversity of galaxy groups and clusters with mass M>1E13/h Msun, in terms of the star formation history of their galaxy populations, for the purpose of constraining the mass scale at which environmentally-important processes play a role in

A Review of Ga₂O₃ Heterojunctions for Deep‐UV Photodetection: Current Progress, Methodologies, and Challenges

Advanced Electronic Materials, EarlyView.
This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

The rotation of Galaxy Clusters [PDF]

Published in Astrofizika, Vol. 58, No. 3, pp. 353-363 (August 2014), 2015
The method for detection of the galaxy cluster rotation based on the study of distribution of member galaxies with velocities lower and higher of the cluster mean velocity over the cluster image is proposed. The search for rotation is made for flat clusters with $a/b>1.8$ and BMI type clusters which are expected to be rotating.

Non‐thermal plasma decontamination of microbes: a state of the art

Biotechnology Progress, EarlyView.
Abstract Microbial decontamination is a critical concern in various sectors, from healthcare to food processing. Traditional decontamination methods, while effective to a degree, present limitations in terms of environmental impact, efficiency, and potential harm to the target material. This review investigates the emerging realm of non‐thermal plasma (
