The scenario that has been selected as the standard cosmological model
is the Lambda Cold Dark Matter (ΛCDM), which provides a remarkable fit
to the bulk of available cosmological data. However, discrepancies among
key cosmological parameters of the model have emerged with different
statistical significance. While some portion of these discrepancies may
be due to systematic errors, their persistence across probes can
indicate a failure of the canonical ΛCDM model. I will review these
tensions, showing some interesting extended cosmological scenarios that
can alleviate them.

This event brings together employers who want to help students (undergrad and grad) from STEM majors explore various career pathways in their industries and answer questions about what they can do with their majors and career interests. Additionally, for students who are seeking internships and summer and post-graduation jobs, these companies also are available to talk about their current openings and how you can apply.

As technological improvements continue to lower manufacturing costs, astrographic telescopes and cameras are becoming cheaper and more accessible to a wider community. The Argus Optical Array (AOA) capitalizes on these advances to create an all-sky, high-cadence telescope array with arcsecond-resolution … Read more

The RESOLVE G3 Group Finding Algorithm and the HI Masses of Galaxy Groups at z~0 Galaxy groups, systems of galaxies occupying a common dark matter halo, are dynamic environments where processes such as large-scale gas accretion, merging, and feedback can … Read more

We test the assumption of entropy conservation between Big Bang nucleosynthesis (BBN) and recombination by considering a massive particle that decays into a mixture of photons and other relativistic species. We employ Planck temperature and polarization anisotropies, COBE/FIRAS spectral distortion … Read more

K2 provided a phenomenal opportunity to study properties of stars in clusters, particularly young low-mass stars, far beyond the expectations of the original Kepler mission. The high-precision photometry provided by K2 allows us to probe stellar variability to lower masses and lower amplitudes than has ever been done before. Younger stars are generally more rapidly rotating and have larger star spots than older stars of similar masses, so spots rotating into and out of view reveal the (surface) rotation rate of these stars. K2 has monitored stars from several clusters, most notably Rho Oph (~1 Myr), Taurus (~5 Myr), USco (~20 Myr), the Pleiades (~125 Myr), and Praesepe (~700 Myr). The light curves have yielded thousands of rotation rates, and revealed far greater diversity in light curves than was anticipated. Now that we have TESS data as well, we can add stars from many more clusters, including the Upper Centaurus-Lupus (UCL) and Lower Centaurus-Crux (LCC) young moving groups (~15 Myr). In this talk, I will review my K2 results including new TESS results from UCL/LCC.
