Simulations of Galaxy Formation in a ΛCDM Universe. III. The Dissipative Formation of an Elliptical Galaxy [PDF]
, 2003 We examine the dynamical structure of an elliptical galaxy simulated in the ΛCDM scenario. The morphology of the galaxy evolves dramatically over time in response to the mode and timing of mass accretion; smooth deposition of cooled gas leads to the ...

Measurement of the Lick Indices in Early-Type Galaxies: Line-of-Sight Velocity Distribution Corrections for IC 1459 [PDF]
Serbian Astronomical Journal, 2009 In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use thelong-slit spectra of the elliptical galaxy IC 1459 from which its kinematicshad previously been extracted to calculate ...

From voids to filaments: environmental transformations of galaxies in the SDSS
, 2017 We investigate the impact of filament and void environments on galaxies, looking for residual effects beyond the known relations with environment density. We quantified the host environment of galaxies as the distance to the spine of the nearest filament,

The SLUGGS Survey: Trails of SLUGGS galaxies in a modified spin-ellipticity diagram [PDF]
, 2017 We present radial tracks for four early-type galaxies with embedded intermediate-scale discs in a modified spin-ellipticity diagram. Here, each galaxy's spin and ellipticity profiles are shown as a radial track, as opposed to a single, flux-weighted aperture-dependent value as is common in the literature.

Plant Pathology, Volume 74, Issue 3, Page 605-640, April 2025.The literature cites many alternative hosts of Phytophthora erythroseptica. However, evidence of host status is often insufficient, thus a polyphasic approach (morphological, molecular, histological and pathogenicity) is required. ABSTRACT Most published studies of Phytophthora erythroseptica, the major causal agent of pink rot of potato, have focused ...

Chandra Observation of M84, a Radio Lobe Elliptical Galaxy in the Virgo Cluster [PDF]
, 2000 We analyzed a deep Chandra observation of M84, a bright elliptical galaxy in the core of the Virgo Cluster. We find that the spatial distribution of the soft X-ray emission is defined by the radio structure of the galaxy.

UV Visibility of Moderate-Redshift Giant Elliptical Galaxies [PDF]
Journal of Astronomy and Space Sciences, 1998 We show quantitatively whether giant elliptical galaxies would be visible at far UV wavelengths if they were placed at moderate redshift of 0.4-0.5. On the basis of simple cosmological tests, we conclude that giant elliptical galaxies can be detectable ...

Galaxy Formation from the Primordial Black Holes
EPJ Web of Conferences, 2017 Supermassive black hole (SMBH) of size MBH = 106-10M⊙ is common in the Universe and it defines the center of the galaxy. A galaxy and the SMBH are generally thought to have co-evolved.

Deep Synoptic Array Science: Two Fast Radio Burst Sources in Massive Galaxy Clusters
The Astrophysical Journal Letters, 2023 The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/submillimeter wavelengths (Sunyaev–Zel’dovich effect) for decades.

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 ...
