The SAURON project - X. The orbital anisotropy of elliptical and lenticular galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
We analyse the orbital distribution of elliptical (E) and lenticular (S0) galaxies using SAURON integral-field stellar kinematics within about one effective (half-light) radius. We construct the anisotropy diagram, which relates the ratio of the ordered and random motion in a galaxy (V/sigma) to its observed ellipticity (epsilon), for the 48 E/S0 ...

Comparison between a handheld ultrasound device and a traditional ultrasound for performing transcranial sonography in patients with Parkinson's disease

Brain and Behavior, Volume 13, Issue 2, February 2023., 2023
Graph 1. The receiver operating characteristic (ROC) curve. The area under the curve is 0.91 with a confidence interval (CI) of 95%: 0.84–0.97. The best substantia nigra cutoff value was 0.20 cm2. Sensitivity = 0.98 and specificity = 0.87. Abstract Objective The aim of this study is to compare a portable ultrasound (US) device and a traditional US for ...

The role of siliciclastics in carbonate fabric diversity and preservation: A case study from the Neoproterozoic carbonate − siliciclastic Horse Thief Springs Formation, Death Valley

Sedimentology, Volume 69, Issue 5, Page 2284-2318, August 2022., 2022
Abstract The sedimentary record of the Pahrump Group in Death Valley comprises well‐exposed successions of mixed carbonate and siliciclastic deposits. Despite the abundance of studies focussing on the depositional dynamics of mixed carbonate – siliciclastic deposition in the Phanerozoic, the record of similar Proterozoic examples is comparatively ...

Bose‐Einstein Condensate Dark Matter Halos Confronted with Galactic Rotation Curves

Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017
We present a comparative confrontation of both the Bose‐Einstein Condensate (BEC) and the Navarro‐Frenk‐White (NFW) dark halo models with galactic rotation curves. We employ 6 High Surface Brightness (HSB), 6 Low Surface Brightness (LSB), and 7 dwarf galaxies with rotation curves falling into two classes.

The Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
A new generation of wide‐field emission‐line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas‐phase emission in nearby late‐type galaxies, based on large samples of HII regions and full two‐dimensional coverage.

Properties of the Photometric Components of Lenticular Galaxies

Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012
After almost one century since their definition, the origin of lenticular galaxies is still a matter of debate. Several formation processes have been proposed in order to explain the wide variety of their observational properties. These properties could indicate that the class of lenticulars is a family formed by galaxies with different formations and ...
