Hot Gas Structure in the Elliptical Galaxy NGC 4472 [PDF]
, 2004 We present X-ray spectroscopic and morphological analyses using Chandra ACIS and ROSAT observations of the giant elliptical galaxy NGC 4472 in the Virgo Cluster. We discuss previously unobserved X-ray structures within the extended galactic corona.

Advanced Science, Volume 12, Issue 46, December 11, 2025.This study explores the therapeutic potential of iNSC‐Exo via local and systemic delivery in TBI mice. It is found that iNSC‐Exo enhances NRXN signaling through Microglia_Nrg3 and Microglia_Rarb, effectively promoting functional and neurological recovery, suggesting a new therapeutic strategy for TBI. Abstract Traumatic brain injury (TBI) poses serious

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 ...

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.A new species Astragalus zhobensis, from Qamardin Karez, Zhob district, northern Balochistan, Pakistan is described and illustrated. The new species is morphologically similar to A. cartilagineus, but can be distinguished by strigose hairs 3–5 mm long, (not stiff 1.5−4.0 mm long hairs); stipules 5–15 mm (not 8−12 mm) long; leaflets in 4–6 pairs, (not 3–

, 1999 Surface photometry has been performed on a sample of 46 field elliptical galaxies. These galaxies are described well by a deVaucouleurs R^{1/4} profile. The sample was selected from the combined Canada-France and LDSS redshift surveys and spans the range

On the Origin of Density Cusps in Elliptical Galaxies [PDF]
, 1998 We investigated the dynamical reaction of the central region of galaxies to a falling massive black hole by N-body simulations. As the initial galaxy model, we used an isothermal King model and placed a massive black hole at around the half-mass radius ...

High resolution soft x-ray spectroscopy of the elliptical galaxy NGC 5044. Results from the reflection grating spectrometer on-board XMM-Newton [PDF]
, 2002 The results from an X-ray spectroscopic study of the giant elliptical galaxy NGC 5044 in the center of a galaxy group are presented. The line dominated soft X-ray spectra (mainly Fe-L and $\ion{O}{viii}$ ${\rm Ly\alpha}$) from the diffuse gas are ...

A Photometric Study of Giant Ellipticals and Their Stellar Halos With VST
Galaxies, 2017 Observations of diffuse starlight in the outskirts of galaxies are thought to be a fundamental source of constraints on the cosmological context of galaxy assembly in the Λ CDM model.
