Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Wenxiu Yang, Yitian Sun, Yougang Wang, Katelin Schutz, Yichao Li | Summary: Axions are one of the leading dark matter candidates. If we are embedded in a Milky Way dark matter halo comprised of axions, their stimulated decay would enable us to observe a counterimage (“axion gegenschein") […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Matilde Lopes Abreu, Michael S. Turner, , , | Summary: The first year results of DESI provide evidence that dark energy may not be quantum vacuum energy ($Lambda$). If true, this would be an extraordinary development in the 25-year quest to understand cosmic acceleration. The best-fit […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Michael Reefe, Michael McDonald, Marios Chatzikos, Jerome Seebeck, Richard Mushotzky | Summary: In the centers of many galaxy clusters, the hot ($sim$10$^7$ K) intracluster medium (ICM) can become dense enough that it should cool on short timescales. However, the low measured star formation rates in massive central […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We present a new approach to symmetry breaking for pairs of real forms of $(GL(n, mathbb{C}), GL(n-1, mathbb{C}))$. While translation functors are a useful tool for studying a family of representations of a single reductive group $G$, when applied […]
Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Constantin Payerne, Zhuowen Zhang, Michel Aguena, Céline Combet, Thibault Guillemin | Summary: Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, weak gravitational lensing has proven to be a powerful tool to constrain the cluster mass-richness relation. This work is […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Feng Yuan, Francesco Tombesi, Fu-guo XIe, | Summary: Theoretical and numerical simulations of black hole hot accretion flows have shown the ubiquitous existence of winds and predicted their properties such as velocity and mass flux. In this paper, we have summarized from literature the physical […]
Kavli Affiliate: David A. Principe | First 5 Authors: Steven M. Silverberg, Scott J. Wolk, David A. Principe, P. Christian Schneider, Hans Moritz Guenther | Summary: HL Tau is one of the most well-studied Class I young stellar objects, including frequent observations at near- and mid-infrared, (sub-) millimeter, and X-ray wavelengths. We present the results […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sean Heston, Nick Ekanger, Shunsaku Horiuchi, , | Summary: We examine the detectability of $gamma$-ray emission originating from the radioactive decays of unstable nuclei that are synthesized in relativistic outflows launched in magneto-rotational core-collapse supernovae. The observed lines have enhanced energies due to the Lorentz boosted nuclei […]
Kavli Affiliate: Tom Abel | First 5 Authors: Kwanit Gangopadhyay, Arka Banerjee, Tom Abel, , | Summary: The $k$-Nearest Neighbour Cumulative Distribution Functions are measures of clustering for discrete datasets that are fast and efficient to compute. They are significantly more informative than the 2-point correlation function. Their connection to $N$-point correlation functions, void probability […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Mansi M. Kasliwal, Nicholas Earley, Roger Smith, Tristan Guillot, Tony Travouillon | Summary: We present Cryoscope — a new 50 sq. deg field-of-view, 1.2 m aperture, K-dark survey telescope to be located at Dome C, Antarctica. Cryoscope has an innovative optical-thermal design wherein the entire telescope […]
