A Proliferated Space Architecture for Time-Domain Astrophysics

Posted by klaurent MIT, This Week: Astrophysics

Kavli Affiliate: Catherine Grant | Summary:Time-Domain and Multi-Messenger Astrophysics (TDAMM) is entering a discovery-rich but follow-up-limited era, creating an urgent need for responsive, multiwavelength space-based capabilities. The Hydra constellation is a concept for a proliferated space architecture for time-domain astrophysics. The constellation would act as a disaggregated observatory composed of coordinated, relatively low-cost spacecraft that […]

Parvalbumin interneurons gate and shape striatal sequences

Posted by dbos This Week: Neuroscience, UCSF

Kavli Affiliate: Joshua Berke | Authors: Mariana Duhne, Isabelle Gonzalez Montalvo, Chelsea S Zheng, Lilian Pelattini and Joshua D Berke | Summary: Impulsive and uncontrolled behaviors are associated with loss of parvalbumin-expressing striatal interneurons (PV+). To understand this microcircuit mechanism we compared spiking of five classes of identified neurons in sensorimotor striatum, as rats waited […]

Clustering-based halo mass assignment for high-redshift galaxies: method, validation, and application to JWST

Posted by klaurent Cambridge, This Week: Astrophysics

Kavli Affiliate: Roberto Maiolino | Summary:We present a clustering-based method for inferring halo masses of high-redshift galaxies, validated using the COLIBRE simulations combined with the HOMA empirical model, which assumes star formation to be proportional to halo accretion rate and is calibrated to JWST observations. Our approach matches the two-point correlation function of galaxies in […]

High-Temperature ferromagnetism from site-selective filling in (Fe,Ni)$_6-δ$GeTe$_2$

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Jeffrey Neaton | Summary:The discovery of high-temperature ferromagnetism in the metallic van der Waals (vdW) system Fe$_N$GeTe$_2$ has brought two-dimensional (2D) magnets into technologically relevant temperature scales. Specifically at N = 5, dilution of magnetic moments by nickel substitution counterintuitively achieves a record high Curie temperature of 478~K. Unraveling the origin of this […]

Hunting the Unseen: Deep Learning Analysis for Semi-Visible Jet Tagging

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: Mihoko Nojiri | Summary:Semi-Visible Jets (SVJs) constitute a distinctive collider signature of strongly interacting dark sectors, embedding Dark Matter candidates, wherein jets contain both visible Standard Model objects and invisible dark hadrons, giving rise to correlated jet activity and missing transverse momentum. In this work, we investigate SVJs produced through a heavy Z’ […]

Out-of-equilibrium relaxation dynamics of the superconducting order parameter in CsV$_3$Sb$_5$

Posted by klaurent Cornell, This Week: Nanoscience

Kavli Affiliate: Brad Ramshaw | Summary:The application of a time-varying strain field drives a superconducting order parameter out of equilibrium. How the order parameter relaxes back to equilibrium depends both on the structure of the superconducting gap and on the nature of quasiparticle scattering. We report the discovery of an ultrasonic attenuation peak inside the […]

No Detectable One-halo Galactic Conformity Signal with Halo-mass Estimates Consistent with Weak-lensing Constraints

Posted by klaurent Cambridge, This Week: Astrophysics

Kavli Affiliate: Roberto Maiolino | Summary:One-halo galactic conformity is the tendency for satellites in halos with quenched centrals to have lower star-formation activity than those in halos with star-forming centrals at fixed halo mass. It is an important probe of the galaxy–halo connection and halo-wide quenching processes that may couple central and satellite evolution. However, […]
