Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster
, 2018 Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a ...

Detection of Far Infrared Emission from Galaxies and Quasars in the Galactic Extinction Map by Stacking Analysis [PDF]
, 2012 We have performed stacking image analyses of galaxies over the Galactic extinction map constructed by Schlegel, Finkbeiner & Davis (1998). We select ~10^7 galaxies in total from the Sloan Digital Sky Survey (SDSS) DR7 photometric catalog. We detect clear

Protein Science, 2009 AbstractMany protein classification systems capture homologous relationships by grouping domains into families and superfamilies on the basis of sequence similarity. Superfamilies with similar 3D structures are further grouped into folds. In the absence of discernable sequence similarity, these structural similarities were long thought to have ...

Asymmetric Star Formation Efficiency Due to Ram Pressure Stripping
Galaxies, 2016 Previous works have shown that a dense cluster environment affects satellite galaxy properties and accelerates or truncates their evolutionary processes.

The effect of dwarf galaxies disruption in semi-analytic models [PDF]
, 2007 We present results for a galaxy formation model that includes a simple treatment for the disruption of dwarf galaxies by gravitational forces and galaxy encounters within galaxy clusters.

The 2dF Galaxy Redshift Survey: power-spectrum analysis of the final data set and cosmological implications [PDF]
, 2005 We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing a direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts.

The Astronomical Journal, 2012 A growing number of low luminosity and low surface brightness astronomical objects challenge traditional notions of both galaxies and star clusters. To address this, we propose a definition of galaxy independent of the cold dark matter model of the universe: A galaxy is a gravitationally bound set of stars whose properties cannot be explained by a ...

The Effect of Immersion Technology on the Quality of Life in Older Adults: A Systematic Review
AGING MEDICINE, EarlyView.Immersive technologies, especially virtual reality (VR), significantly improve the quality of life for older adults by enhancing physical health, cognitive function, and psychological well‐being. These technologies can be adapted to meet individual needs, making them an effective tool for addressing the challenges of aging.
