Cold Neptunes appear to be among the most abundant planets in
the Galaxy, yet their role in shaping planetary systems remains
poorly understood. We study the dynamical evolution of cold Neptune
systems born in resonant chains through disk-driven...
Foundation models like GPT-4 have dramatically altered the
modern work landscape for many industries reliant on language
tasks, but no equivalent model exists yet for scientific
applications. Incorporating foundation models into research
workflows...
Wide-area cosmic microwave background (CMB) surveys are designed
for precision cosmology, but also provide unique opportunities for
time domain astronomy at millimetre (mm) wavelengths. In this talk,
Dr. Hincks will describe how he has used the...
In this talk I will review the current state of and future
prospects for exoplanet demographics. I will walk through the
latest understanding of the frequency of Earth-like planets from
Kepler, and their implications for NASA’s next flagship
mission...
Cosmological data has opened up new vistas on fundamental
physics yet it is limited in its scope. While it has given us
tantalizing hints at how the Universe might be expanding, it is
unclear whether it can ever be used to find the
microphysical...
I will present the first three-dimensional, full-sky dust map
with variations in extinction curves, parameterized by R(V).
Leveraging Gaia XP spectra, we have determined extinction curves
for 130 million stars—two order of magnitude more than...
With increasingly precise measurements of the small-scale cosmic
microwave background (CMB), the kinetic Sunyaev-Zel’dovich (kSZ)
effect has emerged as a powerful probe of cosmology and
astrophysics through cross-correlations with galaxy surveys.
I...
Abstract: Motivated by Swampland conjectures, I
will present a string theory inspired cosmological model with a
coupled dark sector that evolves with a scalar field. When fitted
to the recent DESI DR2 results (together with the CMB data
and...
