Galaxy surveys, which observe the positions and shapes of
galaxies across large areas of the sky, can map a significant
fraction of our cosmic volume. With the recent or imminent start of
several next-generation projects — including LSST, Euclid...
NSF’s Daniel K. Inouye Solar Telescope (DKIST) has just begun
operation and promises exciting new insights into plasma physics on
the sun. In this talk, I will provide an overview of DKIST and the
National Solar Observatory’s Integrated Synoptic...
Radio waves from high redshift are expected to show a rich
signal due to the 21-cm line of intergalactic hydrogen. After
years of theoretical predictions, a large international effort
is now producing the first tentative results. The
coming...
Supernova remnants (SNRs) are believed to produce the most part
of the galactic cosmic rays (CRs). SNRs harbor non-relativistic
collisionless shocks responsible for acceleration of CRs via
diffusive shock acceleration (DSA), in which particles gain...
Radiative turbulent mixing layers arise whenever there is shear
between the different phases in a multiphase medium and radiative
cooling is present. The scaling of the hot gas entrainment rate in
simulations and its surprising convergence...
There has been a surge of interest within the particle-physics
and dark matter communities in axions and axion-like particles
(ALPs). These particles result from a possible extensions to the
Standard Model that may solve the Strong-CP problem, and...
Space plasmas are frequently taken to be weakly collisional or
collisionless. Therefore, an explicit form of viscous dissipation
as in collisional (e.g., MHD) cases cannot be easily defined. A
variety of approaches have attempted to characterize...
On a background Minkowski spacetime, the relativistic Euler
equations are known, for a relatively general equation of state, to
admit unstable homogeneous solutions with finite-time shock
formation. By contrast, such shock formation can be...
Abstract 1: Current techniques for analyzing large photometric
catalogs are generally forced to assume a single, universal stellar
initial mass function (IMF), although the IMF should be expected to
vary depending upon conditions within a star...
