Zoom media briefing Event Horizon Telescope year after capturing the image black hole
2020/4/10
Media are invited to join an April 10 Zoom media briefing with Sheperd S. Doeleman, founding director of the Event Horizon Telescope (EHT), and astrophysicist Michael Johnson to discuss the one-year a...
NSF will join several federal agencies and science organizations June 21 for two back-to-back briefings organized by NASA to provide important solar eclipse viewing safety, travel and science informat...
Stunning exoplanet images and spectra from the first year of science operations with the Gemini Planet Imager (GPI) were featured today in a press conference at the 225th meeting of the American Astro...
Supernova Blast Waves in Low-Density Hot Media: A Mechanism for Spatially Distributed Heating
structure supernova remnants
2014/12/24
Most supernovae are expected to explode in low-density hot media, particularly in galactic bulges and elliptical galaxies. The remnants of such supernovae, although difficult to detect individually, c...
Pions may remain stable under certain conditions in a dense media at zero temperature in the normal phase (non pion superfluid state). The stability condition is achieved when the in-media pion width ...

The radial distributions of temperature, density, and gas entropy among cool-core clusters tend to be quite similar, suggesting that they have entered a quasi-steady state. If that state is regulated ...

A FORTH-AND-BACK IMPLICIT Λ ITERATION IN THE SOLUTION OF RADIATIVE TRANSFER IN SPHERICAL MEDIA
Methods numerical-Radiative transfer-Stars atmospheres
2009/3/11
Forth-and-back implicit Λ-iteration has been developed to solve
radiative transfer (RT) problems with plane-parallel geometry in which there is a
coupling of all RT equations by the scattering term ...
