SN 2020jgb: A Peculiar Type Ia Supernova Triggered by a Helium-shell Detonation in a Star-forming Galaxy

open access: yesThe Astrophysical Journal, 2023
The detonation of a thin (≲0.03 M _⊙ ) helium shell (He-shell) atop a ∼1 M _⊙ white dwarf (WD) is a promising mechanism to explain normal Type Ia supernovae (SNe Ia), while thicker He-shells and less massive WDs may explain some recently observed ...

Retracted: Can the chemical industry solve the climate change?On the role of human energy production, renewable energies, and the potential of chemistry as a solution provider

open access: yesChemie Ingenieur Technik, EarlyView., 2023
Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis

open access: yesHepatology, EarlyView., 2022
Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Cosmological Parameter Constraints from the SDSS Density and Momentum Power Spectra

open access: yesThe Astrophysical Journal, 2023
We extract the galaxy density and momentum power spectra from a subset of early-type galaxies in the Sloan Digital Sky Survey (SDSS) DR7 main galaxy catalog. Using galaxy distance information inferred from the improved fundamental plane described in Yoon

Properties of Galaxies with Peculiar Nuclei [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1967
In a former note (Sersic and Pastoriza 1965) we published the results of a survey of bright southern galaxies which were inspected for peculiarities in their nuclei. Although the sample was small ( 35 galaxies) it suggested a relationship between the existence of a bar and the presence of abnormal features in their nuclei.

Radio Emission in Peculiar Galaxies [PDF]

open access: yesInternational Astronomical Union Colloquium, 1990
During the last decades a number of surveys of peculiar galaxies have been carried out and accurate positions become available. Since peculiarities are a possible evidence of radio emission (Wright, 1974; Sulentic, 1976; Stocke et al.,1978), we have selected a sample of 24 peculiar galaxies with optical jet-like features or extensions in different ...

Shock Enhanced [C ii] Emission from the Infalling Galaxy Arp 25

open access: yesThe Astrophysical Journal, 2023
We present SOFIA observations with HAWC+ and FIFI-LS of the peculiar galaxy Arp 25, also known as NGC 2276 or UGC 3740, whose morphology is deformed by its impact with the intragroup medium of the NGC 2300 galaxy group.

Phosphorus-rich stars with unusual abundances are challenging theoretical predictions

open access: yesNature Communications, 2020
Current models of Galactic chemical evolution under predict the phosphorus we observe in our Solar System. Here, the authors show the discovery of 15 phosphorus-rich stars with a peculiar abundance pattern that challenges the present stellar ...

The JWST Hubble Sequence: The Rest-frame Optical Evolution of Galaxy Structure at 1.5 < z < 6.5

open access: yesThe Astrophysical Journal, 2023
We present results on the morphological and structural evolution of a total of 3956 galaxies observed with JWST at 1.5 < z < 6.5 in the JWST CEERS observations that overlap with the CANDELS EGS field.
