Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Kohei Inayoshi, Jinyi Shangguan, Xian Chen, Luis C. Ho, Zoltan Haiman | Summary: Little red dots (LRDs) are a newly identified class of broad-line active galactic nuclei (AGN) with a distinctive v-shape spectrum characterized by red optical and blue UV continuum emission. Their high abundance at redshifts […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, , , , | Summary: In light of recent DAMIC-M results, we present the status of thermal-relic dark matter $chi$ coupled to a kinetically-mixed dark photon $A^prime$. In the predictive "direct annihilation" regime, $m_{A’} > m_chi$, the relic abundance depends on the kinetic mixing parameter, […]
Kavli Affiliate: Chihway Chang | First 5 Authors: Jazmine Jefferson, Yuuki Omori, Chihway Chang, Shrihan Agarwal, Joe Zuntz | Summary: In recent years, weak lensing shear catalogs have been released by various Stage-III weak lensing surveys including the Kilo-Degree Survey, the Dark Energy Survey, and the Hyper Suprime-Cam Subaru Strategic Program. These shear catalogs have […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Patrick Tamburo, Samuel W. Yee, Juliana García-Mejía, Gudmundur Stefánsson, David Charbonneau | Summary: We measure the true obliquity of TOI-2364, a K dwarf with a sub-Saturn-mass ($M_p = 0.18,M_J$) transiting planet on the upper edge of the hot Neptune desert. We used new Rossiter-McLaughlin observations gathered with […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: J. A. Zebrowski, C. L. Reichardt, A. J. Anderson, B. Ansarinejad, M. Archipley | Summary: We present a measurement of the $B$-mode polarization power spectrum of the cosmic microwave background anisotropies at 32 $le$ $ell$ $<$ 502 for three bands centered at 95, 150, and 220 GHz […]

Haonan Zheng, Shihong Liao, Liang Gao, Fangzhou Jiang, | Summary: [[{“value”:”We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their properties closely match observations. The total masses of EAGLE UDGs range from ${sim}5times 10^{8}~M_{odot}$ to ${sim}2times 10^{11}~M_{odot}$, indicating that they are […]

Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Harry Goodhew, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We uncover a geometric organization of the differential equations for the wavefunction coefficients of conformally coupled scalars in power-law cosmologies. To do this, we introduce a basis of functions inspired by a decomposition of […]
