Exploring A Cosmic-Ray Origin of the Multi-wavelength Emission in M31.

Another possibility is that the emission in M31 can be accounted for with a purely astrophysical cosmic-ray (CR) scenario. This scenario would lead to a rich multi-wavelength emission that can, in turn, be used to test it. Relativistic cosmic-ray electrons (CRe) in magnetic fields produce radio emission through synchrotron radiation, whileRead More →

How Gas Accretion Feeds Galactic Disks. (arXiv:1903.06840v1 [astro-ph.GA]) <a href="http://arxiv.org/find/astro-ph/1/au:+Ho_S/0/1/0/all/0/1">Stephanie H.

Turner</a> Numerous observations indicate that galaxies need a continuous gas supply to fuel star formation and explain the star formation history. However, direct observational evidence of gas accretion remains rare. Using the EAGLE cosmological hydrodynamic simulation suite, we study cold gas accretion onto galaxies and the observational signatures of the cold gas kinematics. For EAGLE galaxies at z=0.27, we find that cold gas accretes onto galaxies anisotropically with typical inflow speeds between 20 km s$^{-1}$ and 60 km s$^{-1}$. Most of these galaxies have comparable massRead More →

The rise and fall of Ziggy star formation and the rich dust from ancient stars Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can’t explain this much dust in a galaxy this young, forcing us to rethink the history of star formation. Researchers now think MACS0416_Y1 experienced staggered star formation with two intense starburst periods 300 million and 600 million years after the Big Bang with a quiet phase in between. phys.org Go to SourceRead More →

The Challenges of Observing, Calibrating, and Modeling Stellar Spectral Energy Distributions. (arXiv:1903.06859v1 [astro-ph.SR]) <a href="http://arxiv.org/find/astro-ph/1/au:+Prieto_C/0/1/0/all/0/1">Carlos Allende Prieto</a> (Instituto de Astrofisica de Canarias) While optical and quantum efficiency are on the rise, and spectrographs becoming massively multiplexed, measuring spectral energy distributions of astronomical sources with accuracy remains a challenge. In addition to atmospheric refraction, extinction, variability, and limited apertures of instrument entrance slits and optical fibers, accurate calibration is hampered by issues such as a limited choice of reliable standard stars. Modeling stellar spectral energy distributions has seen good progress, but some weaknesses survive, especially for late-type stars. This article provides an overview of these mattersRead More →

On the Dynamics of Comets in Extrasolar Planetary Systems. (arXiv:1903.06910v1 [astro-ph.EP]) <a href="http://arxiv.org/find/astro-ph/1/au:+Dvorak_R/0/1/0/all/0/1">Rudolf Dvorak</a>, <a href="http://arxiv.org/find/astro-ph/1/au:+Loibnegger_B/0/1/0/all/0/1">Birgit Loibnegger</a>, <a href="http://arxiv.org/find/astro-ph/1/au:+Cuntz_M/0/1/0/all/0/1">Manfred Cuntz</a> Since very recently, we acquired knowledge on the existence of comets in extrasolar planetary systems. The formation of comets together with planets around host stars now seems evident. As stars are often born in clusters of interstellar clouds, the interaction between the systems will lead to the exchange of material at the edge of the clouds. Therefore, almost every planetary system should have leftover remnants as a result of planetary formation in form of comets at the edges of those systems. These Oort clouds aroundRead More →
