Supernovae, tidal disruption events and merging neutron stars
can provide a wealth of physical insights from nuclear physics to
cosmology; they can teach us about the creation of the elements,
the formation of compact objects, accretion processes...
Matroids are combinatorial abstractions of the notion of linear
independence. They are one of the main objects studied in the
current special year in the School of Mathematics. I will talk
about a notion of scattering amplitudes for matroids. It is...
The search for signs of life beyond Earth is a key motivator in
exoplanet research. A suitable “biosignature gas” is one
that: can accumulate in an atmosphere against atmospheric radicals
and other sinks; has strong atmospheric spectral features...
Over a five-year period, the Dark Energy Spectroscopic
Instrument (DESI) will spectroscopically classify nearly 40 million
galaxies and quasars over 1/3 of the sky and to redshifts z 3.5.
The DESI collaboration has completed measurements of the...
The possibility that some of the black holes in the universe
have a non-stellar origin and that they play a significant role in
cosmology - including being some or all of the dark matter - is
both timely and intriguing. I will review the status of...
I will discuss dilaton gravity with a sine potential, where
periodic shifts of the dilaton (that leave the potential invariant)
are treated as a redundancy. Most things I will say hold true for
generic periodic potentials, but the sine potential is...
