A peculiar galaxy appears at redshift 11: properties of a moderate-redshift interloper★ [PDF]
, 2012 In 2011 Laporte et al. reported a very high redshift galaxy candidate: a lensed J-band dropout (A2667-J1). J1 has a photometric redshift of z= 9.6–12, the probability density function for which permits no low- or intermediate-z solution.

Chemie 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.

Two peculiar fast transients in a strongly lensed host galaxy [PDF]
, 2017 A massive galaxy cluster can serve as a magnifying glass for distant stellar populations, as strong gravitational lensing magnifies background galaxies and exposes details that are otherwise undetectable. In time-domain astronomy, imaging programmes with

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

An Unbiased Estimator of Peculiar Velocity with Gaussian Distributed Errors for Precision Cosmology [PDF]
, 2014 We introduce a new estimator of the peculiar velocity of a galaxy or group of galaxies from redshift and distance estimates. This estimator results in peculiar velocity estimates which are statistically unbiased and that have errors that are Gaussian ...

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

Phosphorus-rich stars with unusual abundances are challenging theoretical predictions
Nature 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 ...

Magnetic fields in barred galaxies III. The southern peculiar galaxy NGC 2442 [PDF]
, 2003 Observations of the southern peculiar galaxy NGC 2442 with the Australia Telescope Compact Array in total and linearly polarized radio continuum at λ6 cm are presented and compared with previously obtained Ha data. The distribution of polarized emission,

Radio Emission in Peculiar Galaxies [PDF]
International 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 ...

Threshold Star-Formation Effects in the Peculiar Galaxy ARP 10 (= VV 362) [PDF]
, 1993 We present images of the peculiar galaxy Arp 10 which reveal two rings of concurrent star formation. Apart from a bright ring visible on early photographs of the system, an even brighter inner ring of H II regions is found within the nuclear bulge of the
