Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Daniel Harlow, Hirosi Ooguri, , , | Summary: In this paper we use Euclidean gravity to derive a simple formula for the density of black hole microstates which transform in each irreducible representation of any finite gauge group. Since each representation appears with nonzero density, this gives […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Renske Smit, Roberto Maiolino, Mirko Curti, Nicolas Laporte | Summary: We present a detailed spectroscopic analysis of a galaxy at $z simeq 4.88$ that is, by chance, magnified $sim 30 times$ by gravitational lensing. Only three sources at $z gtrsim 5$ are known with such […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Thomas Siegert, Roland M. Crocker, Oscar Macias, Fiona H. Panther, Francesca Calore | Summary: We use 15 years of $gamma$-ray data from INTEGRAL/SPI in a refined investigation of the morphology of the Galactic bulge positron annihilation signal. Our spatial analysis confirms that the signal traces the old […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Giacomo Principe, Nicola Omodei, Niccolò Di Lalla, Leonardo Di Venere, Francesco Longo | Summary: Fast radio bursts (FRBs) are one of the most exciting new mysteries of astrophysics. Their origin is still unknown, but recent observations seems to link them to Soft Gamma Repeaters and, in particular, […]
Kavli Affiliate: Erin Kara | First 5 Authors: Lars Lund Thomsen, Jane Lixin Dai, Erin Kara, Chris Reynolds, | Summary: X-ray reverberation is a powerful technique which maps out the structure of the inner regions of accretion disks around black holes using the echoes of the coronal emission reflected by the disk. While the theory […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Charles D. Brown, Shao-Wen Chang, Malte N. Schwarz, Tsz-Him Leung, Vladyslav Kozii | Summary: The band structure of a crystal may have points where two or more bands are degenerate in energy and where the geometry of the Bloch state manifold is singular, with consequences for […]
Kavli Affiliate: Gijsje H. Koenderink | First 5 Authors: Iain Muntz, Michele Fenu, Gerjo J. V. M. van Osch, Gijsje H. Koenderink, | Summary: Living tissue is able to withstand large stresses in everyday life, yet it also actively adapts to dynamic loads. This remarkable mechanical behaviour emerges from the interplay between living cells and […]

Kavli Affiliate: John D. Silverman | First 5 Authors: Junyao Li, John D. Silverman, Xuheng Ding, Michael A. Strauss, Andy Goulding | Summary: We measure the evolution of the $M_{rm BH}-M_*$ relation using 584 uniformly-selected SDSS quasars at $0.2<z<0.8$. The black-hole masses ($M_{rm BH}$) are derived from the single-epoch virial mass estimator using the H$beta$ […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Michael Fausnaugh, Ed Morgan, Roland Vanderspek, Joshua Pepper, Christopher J. Burke | Summary: We describe the target selection procedure by which stars are selected for 2-minute and 20-second observations by TESS. We first list the technical requirements of the TESS instrument and ground systems processing that […]
