Abstract Stellar streams that emerge from globular clusters (GCs) are thin stellar structures spread along the orbits of progenitor clusters. Numerical modeling these is essential for understanding their interaction with host galaxy's mass distribution. Traditional methods either computationally expensive or oversimplified, motivating us to develop a fast and accurate approach using particle spray algorithm. By conducting series N -body simulations GCs orbiting galaxy, we find position...
Abstract Retinitis pigmentosa (RP) is a group of blinding disorders caused by diverse mutations, including in rhodopsin ( RHO ). Effective therapies have yet to be discovered. The I307N Rho mouse light-inducible model autosomal dominant RP. Our purpose was describe the glial response this educate future experimentation. mice were exposed 20,000 lx light for thirty minutes induce retinal degeneration. Immunofluorescence staining cross-sections and flat-mounts performed visualize microglia...
Purpose: The I307N rhodopsin (Rho) mouse is a light-inducible model of autosomal dominant retinitis pigmentosa (adRP) that may be useful in testing therapies. We investigated the time-course retinal changes Rho with spectral-domain optical coherence tomography (SD-OCT). Methods: SD-OCT was performed up to day 30 after light damage; electroretinography (ERG) employed evaluate photoreceptor function. utilized ImageJ analyze reflectivity retina. used and electron microscopy assess organization....
ABSTRACT The recent discovery of TeV emission from gamma-ray bursts (GRBs) by the MAGIC and H.E.S.S. Cherenkov telescopes confirmed that these transients can extend to very high energies. energy domain reaches most sensitive band Telescope Array (CTA). This newly anticipated, improved sensitivity will enhance prospects gravitational-wave follow-up observations CTA probe particle acceleration high-energy binary black hole neutron star mergers, stellar core-collapse events. Here we discuss...
Abstract We use the TNG50 and dark matter (DM)-only simulations from IllustrisTNG simulation suite to conduct an updated survey of halo figure rotation in presence baryons. develop a novel methodology detect coherent about arbitrary axis for durations, we apply it catalog 1577 DM halos DM-only run 1396 DM+baryons (DM+B) that are free major mergers. Figure was detected 94% 82% DM+B halos. The pattern speeds rotations lasting ≳1 h −1 Gyr were log-normally distributed with medians 0.25 km s kpc...
Dark matter (DM) bars that shadow stellar have been previously shown to form in idealized simulations of isolated disk galaxies. Here, we show DM commonly occur barred galaxies the TNG50 cosmological simulation suite, but do not appear unbarred Consistent with simulations, are typically shorter than their counterparts and $75\%$ weaker as measured by Fourier $A_2$ moment. dominate shape inner halo potential easily identified time series quadrupolar coefficients. We present two novel methods...
Abstract Dark matter (DM) bars that shadow stellar have been previously shown to form in idealized simulations of isolated disk galaxies, but yet be studied a fully cosmological context. In this work, we analyze population galaxies within the TNG50 simulation determine characteristics their dark bars. We estimate bar strength and orientation using both in-plane Fourier A 2 density moments quadrupolar coefficients spherical harmonic basis function expansions density. additionally present two...
