It was suggested over thirty years ago that microscopic black
holes can exponentially enhance the decay rate of a metastable
false vacuum. The interest in this phenomenon has revived recently
due to its possible phenomenological relevance for the...
The origin of multiple stellar populations (MPs) in globular
clusters (GCs) is one of the most puzzling issues of stellar
astrophysics. Several attempts to understand their formation have
been done both from observational and theoretical studies...
What happens to planets when their stars begin to die? For many
of the planets we’ve discovered outside our Solar System, the
answer is a trip into the fiery depths of their host star,
particularly when that star becomes a red giant. What
happens...
In this talk, I'll discuss our recent work on the Terrestrial
Reconnection Experiment (TREX) where magnetic reconnection is
explored with asymmetric inflow conditions and in a configuration
where the absolute rate of reconnection is set by an...
Abstract: Supermassive black holes create powerful jets of
radiation and plasma particles that move close to the speed of
light. The answers to the questions “how exactly are jets powered
by energy extraction from a black hole” and “what are the...
Relativistic plasmas are central to the study of black hole
accretion, jet physics, neutron star mergers, and compact object
magnetospheres. Going beyond common approaches used in the
literature, I will describe a fully relativistic covariant
14...
I will present a review of how deep learning is used in
astrophysics, and how this use is often misguided. I will introduce
the term “scientific debt,” and argue that, though deep learning
can quickly solve a complex problem, its success does not...
In this talk, I will briefly discuss our work on understanding
the 3D morphology of magnetic fields associated with molecular
clouds. To study the 3D magnetic fields, we first proposed and
demonstrated a new technique to determine the line-of-sight...
The 21 cm line of atomic hydrogen (HI) provides a powerful probe
of the cool-to-warm interstellar gas in galaxies. Virtually all
star-forming galaxies contain a cool neutral component of their
interstellar medium representing the fuel reservoir from...
