Pulsars are rotating magnetic neutron stars which produce
powerful beams of coherent radio emission. They are also prolific
sources of broadband high-energy emission. In this talk I will
describe recent advances in modelling pulsar radio emission...
In this talk I will present a kinetically mixed dark sector
(KMIX) model aimed at simultaneously addressing the Hubble and
S8 tensions. Inspired from string theory, the model includes
two fields: an axion, which plays a role similar to the
scalar...
The importance of star formation “feedback” to the energetics of
the interstellar medium (ISM) has been appreciated throughout the
modern history of astronomy. Star formation is inefficient in gas
consumption because feedback efficiently maintains...
Super star clusters with masses > 1e6 Msun are thought to be
progenitors of globular clusters (GCs). Their births however are
seldomly seen in the local Universe. Given radiation and kinetic
feedbacks that regulate star formation, contribution to...
The understanding of
strongly-correlated quantum matter has challenged
physicists for decades. The discovery four years ago of correlated
phases and superconductivity in magic angle twisted
bilayer graphene has led to the emergence of a new...
Abstract: One of the unique features of
quantum gravity is the lack of local observables and completeness
of boundary observables (e.g. S-matrix in flat space or CFT
correlators in AdS). I will show that the existence of such
boundary observables is...
Abstract: The bootstrap program leverages
symmetry and positivity to carve out the space of
consistent quantum theories. In this talk I will highlight some of
its recent successes, ranging from the numerical solution of
statistical models at...
