FASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022 Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

The Environments of Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1996 In the unified schemes of AGNs BL Lac objects are believed to be Fanaroff-Riley (FR) type I radio galaxies with a relativistic jet aligned to the observer's line of sight (e.g. Urry & Padovani 1995). Kollgaard et al. (1992) and Owen et al. (1995) suggest some FR II sources can also be BL Lac parents. Clearly, isotropic properties such as the galaxy

High energy emission component, population, and contribution to the extragalactic gamma-ray background of gamma-ray emitting radio galaxies [PDF]
, 2022 In this study, we systematically studied the X-ray to GeV gamma-ray spectra of 61 {\it Fermi} Large Area Telescope (LAT) detected radio galaxies. We found an anticorrelation between peak frequency and peak luminosity in the high-energy spectral component of radio galaxies, similar to blazars. With this sample, we also constructed a gamma-ray luminosity

Radio Galaxy Zoo: machine learning for radio source host galaxy cross-identification [PDF]
, 2018 We consider the problem of determining the host galaxies of radio sources by cross-identification. This has traditionally been done manually, which will be intractable for wide-area radio surveys like the Evolutionary Map of the Universe. Automated cross-

The fundamental plane of radio galaxies [PDF]
Astronomy & Astrophysics, 2001 We collected photometrical and dynamical data for 73 low red-shift (z<0.2) Radio Galaxies (LzRG) in order to study their Fundamental Plane (FP). For 22 sources we also present new velocity dispersion data, that complement the photometric data given in our previous study of LzRG (Govoni et al. 2000a). It is found that the FP of LzRG is similar to the

Dynamics of Powerful Radio Galaxies
Galaxies, 2023 Analytical models describing the dynamics of lobed radio sources are essential for interpretation of the tens of millions of radio sources that will be observed by the Square Kilometre Array and pathfinder instruments. We propose that historical models can be grouped into two classes in which the forward expansion of the radio source is driven by ...

Radio Galaxy Zoo: new giant radio galaxies in the RGZ DR1 catalogue [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT In this paper, we present the identification of five previously unknown giant radio galaxies (GRGs) using Data Release 1 of the Radio Galaxy Zoo citizen science project and a selection method appropriate to the training and validation of deep learning algorithms for new radio surveys.

A single fast radio burst localized to a massive galaxy at cosmological distance [PDF]
Science, 2019 Pinpointing a single fast radio burst Fast radio bursts (FRBs) are flashes of radio emission from distant astronomical sources. Two FRBs are known to have repeated, but most last just a few milliseconds and are never seen again.

Nonthermal Emissions from a Head–Tail Radio Galaxy in 3D Magnetohydrodynamic Simulations
The Astrophysical Journal, 2023 We present magnetohydrodynamic simulations of a jet–wind interaction in a galaxy cluster and the radio to gamma-ray and neutrino emissions from this “head–tail galaxy.” Our simulation follows the evolution of cosmic-ray (CR) particle spectra with energy ...

Developing and adult reef fish show rapid light‐induced plasticity in their visual system
Molecular Ecology, Volume 32, Issue 1, Page 167-181, January 2023., 2023 Abstract The visual capabilities of fish are optimized for their ecology and light environment over evolutionary time. Similarly, fish vision can adapt to regular changes in light conditions within their lifetime, e.g., ontogenetic or seasonal variation.
