The SLUGGS Survey: Understanding Lenticular Galaxy Formation via Extended Stellar Kinematics
Galaxies, 2017 We present the latest published and preliminary results from the SLUGGS Survey discussing the formation of lenticular galaxies through analysis of their kinematics.

THE RELATION BETWEEN COMPACT, QUIESCENT HIGH-REDSHIFT GALAXIES AND MASSIVE NEARBY ELLIPTICAL GALAXIES: EVIDENCE FOR HIERARCHICAL, INSIDE-OUT GROWTH [PDF]
, 2009 Recent studies have shown that massive quiescent galaxies at high redshift are much more compact than present-day galaxies of the same mass. Here we compare the radial stellar density profiles and the number density of a sample of massive galaxies at z ∼

The macroscopical anatomy of the lungs and thorax of the African lion (Panthera leo)
Acta Zoologica, Volume 105, Issue 4, Page 482-495, October 2024.Abstract The left and right lungs extend from the second rib to the 13th, while only a small portion is present cranial to the 4th rib. The basal border of the left lung extends horizontally from the second costochondral junction (CCJ) to just ventral to the seventh CCJ, and then dorso‐caudally to the angle of the 13th rib. The right lung has a similar

Disks Controlling Chaos in a 3D Dynamical Model for Elliptical Galaxies
Open Astronomy, 2011 A 3D dynamical model with a quasi-homogeneous core and a disk component is used for the chaos control in the central parts of elliptical galaxy.

Constraints on Elliptical Galaxy Formation from the Properties of Their Globular Cluster Systems [PDF]
arXiv, 1996 Globular clusters are valuable fossil records of the formation and evolution of their host galaxies. The color distribution of elliptical galaxy globular cluster systems indicates an episodic formation history, consistent with a merger origin for these galaxies.

Bufonia darvishii (Caryophyllaceae), a novel endemic species from Zagros Mountains, Iran
Nordic Journal of Botany, Volume 2024, Issue 10, October 2024.A new subalpine species of Bufonia sect. Longipedicellata from the Zagros Mountains in west Iran is described and illustrated here. It colonizes mountain slopes with gravelly, stony, and scree substrates in one locality of Chaharmahal and Bakhtiari province, preferably with a western and north‐west orientation, at elevations between 2700 and 3100 m a.s.

Core Formation by Binary Scouring and Gravitational Wave Recoil in Massive Elliptical Galaxies
The Astrophysical JournalScouring by supermassive black hole (SMBH) binaries is the most accepted mechanism for the formation of the cores seen in giant elliptical galaxies. However, an additional mechanism is required to explain the largest observed cores.

Pride of the East: Motorcycle Speedway, Transnational Encounters and Provincial Heartlands
History, Volume 109, Issue 386-387, Page 335-366, September 2024.Abstract For a century, speedway has operated on a transnational basis. Its riders, competitions and machinery regularly traverse national and continental borders. The imposition of the Cold War's Iron Curtain did little to impede its growth. This article focuses on one of speedway's far‐flung and diverse provincial heartlands to show how the sport ...

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution
The Astrophysical JournalCorrelation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) with the burgeoning field of causal discovery.

On The Parent Population of Radio Galaxies and the FR I--II Dichotomy [PDF]
arXiv, 2001 The possibility of radio galaxies being random sample of otherwise normal elliptical galaxies is tested. Starting with the observed optical luminosity functions for elliptical galaxies, it is shown that the probability of an elliptical forming a radio source is a continuous, increasing function of optical luminosity, precisely proportional to square of
