The group plans to meet in person in the
PGI space (Jadwin, 4th floor), a boxed lunch
will be provided in order to accommodate the earlier start
time. There is also a zoom link for those who can’t...
The black hole information paradox — whether information escapes
an evaporating black hole or not — remains one of the greatest
unsolved mysteries of theoretical physics. The apparent conflict
between validity of semiclassical gravity at low...
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...
