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: Kohei Inayoshi | First 5 Authors: Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski, Hollis B. Akins, Fergus Cullen | Summary: We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a $z=9.288$ broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam photometry, follow-up NIRSpec/PRISM spectroscopy […]

Kavli Affiliate: Michael L. Roukes | First 5 Authors: Andrew N. Cleland, Michael L. Roukes, , , | Summary: We describe a method with which to fabricate sub-micron mechanical structures from silicon-on-insulator substrates. We believe this is the first reported method for such fabrication, and our technique allows for complex, multilayer electron beam lithography to […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Xin Chen, Xin Chen, , , | Summary: In our recent experimental work (Appl. Phys. Lett. 125, 122109 (2024)), we observed that crystalline Si$_3$N$_4$ cap layers a few nanometers thick can form in situ on GaN surfaces. Compared with amorphous SiO$_2$ and Al$_2$O$_3$ caps, these crystalline caps […]
Kavli Affiliate: Hu Zhan | First 5 Authors: Hang Zhou, Xin Wang, Matthew A. Malkan, Tommaso Treu, Yiming Yang | Summary: The MAMMOTH-MOSFIRE program is a deep Keck MOSFIRE K-band spectroscopic follow-up of emission-line galaxies identified in the MAMMOTH-Grism HST WFC3/G141 slitless spectroscopic survey, targeting the core regions of three most massive galaxy protoclusters at […]
Kavli Affiliate: Hu Zhan | First 5 Authors: Hang Zhou, Hang Zhou, , , | Summary: The MAMMOTH-MOSFIRE program is a deep Keck/MOSFIRE K-band spectroscopic follow-up of emission-line galaxies identified in the MAMMOTH-Grism HST/WFC3 G141 slitless spectroscopic survey, targeting the core regions of three most massive galaxy protoclusters at cosmic noon. To introduce this program, […]
Kavli Affiliate: Roland Vanderspek | First 5 Authors: Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang, Emma Nabbie, George Zhou | Summary: We present the eccentricity distribution of warm sub-Saturns (4-8 Re, 8-200 day periods) as derived from an analysis of transit light curves from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. We use the […]
