Kavli Affiliate: Herman L. Marshall | First 5 Authors: Niccolò Di Lalla, Niccolò Di Lalla, , , | Summary: We present the X-ray polarization observation of G21.5-0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in October 2023, with a total livetime of approximately 837 ks. Using different analysis […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Davide Costa, Davide Costa, , , | Summary: Ge and Si strained quantum wells have enabled the most advanced spin-qubit quantum processors, but they are deposited on defective, metamorphic SiGe substrates, which may impact device performance and scaling. Here we introduce an alternative platform, based on a […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: , , , , | Summary: We report the delivery to the Mikulski Archive for Space Telescopes (MAST) of tables containing Root Mean Square (RMS) Combined Differential Photometric Precision (CDPP) values for all TESS 2-min cadence targets with Science Processing Operations Center (SPOC) light curves in […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Sergio Martin-Alvarez, Sergio Martin-Alvarez, , , | Summary: Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation histories make them especially sensitive to the processes that regulate baryons through multi-phase outflows. Using high-resolution, cosmological zoom-in […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Roberto Maiolino, Roberto Maiolino, , , | Summary: The recent discovery of a large number of massive black holes within the first two billion years after the Big Bang, as well as their peculiar properties, have been largely unexpected based on the extrapolation of the properties of […]
Kavli Affiliate: Subo Dong | First 5 Authors: Jinxiao Qin, Jinxiao Qin, , , | Summary: Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-host stars (HS) and isolated stars (IS) with no detected planets, […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Jahmall Bersini, Jahmall Bersini, , , | Summary: We study the fixed point of the three-dimensional NJL model in a double-scaling limit where both the charge $Q$ and the number of fermion flavors $N$ become large with a fixed ratio $q=Q/(2N)$. While a similar analysis has been […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: , , , , | Summary: Young star clusters can inherit bulk rotation from the molecular clouds from which they have formed. This rotation can affect the long-term evolution of a star cluster and its constituent stellar populations. In this study, we aim to characterize the effects […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sydney Jenkins, Sydney Jenkins, , , | Summary: Though missions such as Kepler, K2, and TESS have discovered $>$2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P$lesssim$3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Zubia Hasan, Zubia Hasan, , , | Summary: Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interference. One particularly compelling family of such materials is the half-valence spinel Li$B_2$O$_4$ materials. […]
