Dense Molecular Gas in Lenticular Galaxies [PDF]
Publications of the Astronomical Society of Japan, 2002 We made CO and HCN simultaneous observations of lenticular galaxies (NGC 404, NGC 3593, and NGC 4293) and detected HCN emission in NGC 3593 and NGC 4293 as well as CO in all the galaxies. The $I_\mathrm{HCN} / I_\mathrm{CO}$ ratios were $0.025 \pm 0.006$ and $0.066 \pm 0.005$ in NGC 3593 and NGC 4293, respectively, which are comparable to that of late ...

Radio‐Wave Propagation in Salt Domes: Implications for a UHE Cosmic Neutrino Detector
Advances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014 Salt deposits can be used as a natural dielectric medium for a UHE cosmic neutrino radio detector. Such a detector relies on the capability of reconstructing the initial characteristics of the cosmic neutrino from the measured radio electrical field produced at neutrino’s interaction in salt by the subsequent particle shower.

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.

Creating lenticular galaxies with major mergers [PDF]
, 2016 Lenticular galaxies (S0s) represent the majority of early-type galaxies in the local Universe, but their formation channels are still poorly understood. While galaxy mergers are obvious pathways to suppress star formation and increase bulge sizes, the marked parallelism between spiral and lenticular galaxies (e.g.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Implications and Applications of Kinematic Galaxy Scaling Relations
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 Galaxy scaling relations, which describe a connection between ostensibly unrelated physical characteristics, testify to an underlying order in galaxy formation that requires understanding. I review the development of a scaling relation that (1) unites the well‐known fundamental plane (FP) relation of giant elliptical galaxies and Tully‐Fisher (TF ...

Advances in Astronomy, Volume 2025, Issue 1, 2025.The Chelyabinsk meteor entered Earth’s atmosphere on 15 February 2013, producing a shock wave that injured about 1500 people and damaged thousands of buildings. Despite its relatively large size (∼20 m), the progenitor asteroid approached Earth undetected. Its apparent radiant was too close to the Sun for standard ground‐based near‐Earth asteroid (NEA)

The Baryonic Halos of Isolated Elliptical Galaxies
Galaxies, 2017 Without the interference of a number of events, galaxies may suffer in crowded environments (e.g., stripping, harassment, strangulation); isolated elliptical galaxies provide a control sample for the study of galaxy formation.

STELLAR NUCLEI AND INNER POLAR DISKS IN LENTICULAR GALAXIES [PDF]
The Astronomical Journal, 2016 ABSTRACT I analyze statistics of the stellar population properties for stellar nuclei and bulges of nearby lenticular galaxies in different environments by using panoramic spectral data of the integral-field spectrograph SAURON retrieved from the open archive of the Isaac Newton Group.
