Breaking baryon-cosmology degeneracy with the electron density power spectrum

Kavli Affiliate: David N. Spergel | First 5 Authors: Andrina Nicola, Francisco Villaescusa-Navarro, David N. Spergel, Jo Dunkley, Daniel Anglés-Alcázar | Summary: Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that are robust against these uncertainties, or constrain these […]

TESS Giants Transiting Giants II: The hottest Jupiters orbiting evolved stars

Kavli Affiliate: Alan M. Levine | First 5 Authors: Samuel K. Grunblatt, Nicholas Saunders, Meng Sun, Ashley Chontos, Melinda Soares-Furtado | Summary: Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are not well known. Here we present […]

All-optical ultrafast ReLU function for energy-efficient nanophotonic deep learning

Kavli Affiliate: Alireza Marandi | First 5 Authors: Gordon H. Y. Li, Ryoto Sekine, Rajveer Nehra, Robert M. Gray, Luis Ledezma | Summary: In recent years, the computational demands of deep learning applications have necessitated the introduction of energy-efficient hardware accelerators. Optical neural networks are a promising option; however, thus far they have been largely […]

Closing the spontaneous-scalarization window with binary pulsars

Kavli Affiliate: Lijing Shao | First 5 Authors: Junjie Zhao, Paulo C. C. Freire, Michael Kramer, Lijing Shao, Norbert Wex | Summary: Benefitting from the unequaled precision of the pulsar timing technique, binary pulsars are important testbeds of gravity theories, providing some of the tightest bounds on alternative theories of gravity. One class of well-motivated […]

Reconstructing the polar interface of infinite-layer nickelate thin films

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Berit H. Goodge, Benjamin Geisler, Kyuho Lee, Motoki Osada, Bai Yang Wang | Summary: Nickel-based superconductors provide a long-awaited experimental platform to explore possible cuprate-like superconductivity. Despite similar crystal structure and $d$ electron filling, these systems exhibit several differences. Nickelates are the most polar layered oxide […]

The ALMaQUEST Survey IX: The nature of the resolved star forming main sequence

Kavli Affiliate: Roberto Maiolino | First 5 Authors: William M. Baker, Roberto Maiolino, Asa F. L. Bluck, Lihwai Lin, Sara L. Ellison | Summary: We investigate the nature of the scaling relations between the surface density of star formation rate ($Sigma _{rm SFR}$), stellar mass ($Sigma _*$), and molecular gas mass ($Sigma _{rm H_2}$), aiming […]

Systematic exploration of heavy element nucleosynthesis in protomagnetar outflows

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Nick Ekanger, Mukul Bhattacharya, Shunsaku Horiuchi, , | Summary: We study the nucleosynthesis products in neutrino-driven winds from rapidly rotating, highly magnetised and misaligned protomagnetars using the nuclear reaction network SkyNet. We adopt a semi-analytic parameterized model for the protomagnetar and systematically study the capabilities of its […]

A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS

Kavli Affiliate: George R. Ricker | First 5 Authors: Thomas G. Wilson, Elisa Goffo, Yann Alibert, Davide Gandolfi, Andrea Bonfanti | Summary: We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise the system, we performed and retrieved CHEOPS, TESS, […]
