Bar fraction in lenticular galaxies: dependence on luminosity and environment [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2010
We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the SDSS-DR 7 and 2MASS in optical and near-infrared bands, respectively. We found a bar in 15% of the lenticular galaxies in our sample, which is consistent with recent studies.

NGC 1436: the making of a lenticular galaxy in the Fornax cluster [PDF]

Monthly Notices of the Royal Astronomical Society, 2023
We study the evolutionary path of the Fornax cluster galaxy NGC 1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts an inner star-forming disc and an outer quiescent disc, and we analyse data

PGC 44685: A Dwarf Star-forming Lenticular Galaxy with a Wolf–Rayet Population

The Astrophysical Journal
Lenticular galaxies (S0s) are formed mainly from the gas stripping of spirals in the cluster. But how S0s form and evolve in the field is still in need of being resolved.

A Chandra Observation of the Nearby Lenticular Galaxy NGC 5102: Where are the X-ray Binaries? [PDF]

, 2005
We present results from a 34 ks Chandra/ACIS-S observation of the nearby (d=3.1 Mpc) lenticular galaxy NGC 5102, previously shown to have an unusually low X-ray luminosity.

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies [PDF]

The Astrophysical Journal Letters, 2023
Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

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

Brain Behav, 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 ...

Asymmetric Star Formation Triggered by Gas Inflow in a Barred Lenticular Galaxy PGC 34107 [PDF]

Astrophysical Journal, 2022
Comparing the inactive and gas-poor normal lenticular galaxies (S0s) in the local universe, we study a barred star-forming S0 galaxy, PGC 34107, which has been observed by the Centro Astronómico Hispano Alemán 3.5 m telescope and the Northern Extended ...

Laboratory exploration of mineral precipitates from Europa's subsurface ocean. [PDF]

J Appl Crystallogr, 2021
Precipitation experiments from a model Europan ocean solution subjected to fast and slow freezing suggest that the highly hydrated Na–Mg sulfate phase Na2Mg(SO4)2·16H2O is one of the lowest‐temperature mineral phases likely to be stable on Europa's surface and may therefore be astrobiologically significant.The precipitation of hydrated phases from a ...

Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535 [PDF]

The Astrophysical Journal
Lenticular galaxies (S0s) in the local Universe are generally absent of recent star formation and lack molecular gas. In this paper, we investigate one massive ( M _* ∼ 5 × 10 ^10 M _⊙ ) star-forming S0, PGC 39535, with the Northern Extended Millimeter ...

Luminosities of Barred and Unbarred S0 Galaxies [PDF]

, 2012
Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in the infrared.
