Confirmation of Enhanced Dwarf-sensitive Absorption Features in the Spectra of Massive Elliptical Galaxies: Further Evidence for a Non-universal Initial Mass Function

, 2011
We recently found that massive cluster elliptical galaxies have strong Na I 8183,8195 and FeH 9916 Wing-Ford band absorption, indicating the presence of a very large population of stars with masses

Multimodality Imaging for Transcatheter Tricuspid Regurgitation Interventions: Novel Approaches to the Forgotten Valve

Echocardiography, Volume 41, Issue 12, December 2024.
Central Illustration: The role of multimodality imaging for transcatheter tricuspid valve interventions (TTVI): echocardiography is used for the evaluation of the severity and mechanism of tricuspid regurgitation (TR), for the assessment of the pulmonary pressure and right ventricular (RV) function and for anatomical feasibility for transcatheter ...

Development of hard X‐ray photoelectron spectroscopy in liquid cells using optimized microfabricated silicon nitride membranes

Journal of Synchrotron Radiation, Volume 31, Issue 6, Page 1505-1513, November 2024.
We have developed and successfully tested new environmental liquid cells for HAXPES studies using specially designed thin, low‐stress silicon nitride membranes (15 to 25 nm thickness). The novel aspect is the fabrication of the membranes considering the geometry of the experimental setup, the dimensions of the beam and the use of platinum stripes to ...

Automatic Detection of Galaxy Type From Datasets of Galaxies Image Based on Image Retrieval Approach

Scientific Reports, 2017
This paper presents a new approach for the automatic detection of galaxy morphology from datasets based on an image-retrieval approach. Currently, there are several classification methods proposed to detect galaxy types within an image.

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

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution

The Astrophysical Journal
Correlation 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.

Scaling Relations of Early-Type Galaxies in MOND

Galaxies
We investigate the shape and morphology of early-type galaxies (ETGs) within the framework of Modified Newtonian Dynamics (MOND). Building on our previous studies, which demonstrated that the monolithic collapse of primordial gas clouds in MOND produces ...

Empirical Models for Dark Matter Halos. III. The Kormendy relation and the log(rho_e)-log(R_e) relation

, 2006
We have recently shown that the 3-parameter density-profile model from Prugniel & Simien provides a better fit to simulated, galaxy- and cluster-sized, dark matter halos than an NFW-like model with arbitrary inner profile slope gamma (Paper I).
