Kavli Affiliate: Luis Ho | Summary:A significant puzzle in extragalactic astronomy is the scarcity of Little Red Dots (LRDs) at $z < 3$, compared to their higher abundance at earlier epochs. To understand this transition, we investigate the cosmic evolution of LRD environments. We measure the overdensity for LRDs and the general galaxy population at […]
Kavli Affiliate: Roberto Maiolino | Summary:The rapid accumulation of massive dust reservoirs in the early Universe remains a major challenge in astrophysics. While core-collapse supernovae can inject large dust grains ($a gtrsim 0.1,μrm m$) on short timescales, explaining the total dust budgets in the early Universe likely requires efficient grain growth in the interstellar medium […]
Kavli Affiliate: Dheeraj Pasham | Summary:The repeated tidal stripping of a star by a supermassive black hole, known as a repeating partial tidal disruption event (rpTDE), can give rise to a transient that rebrightens months to years after the first outburst. Among the rpTDE candidates so far observed, some exhibit dimmer peak luminosities during each […]
Kavli Affiliate: Chiara Daraio | Summary:Metamaterials can achieve exceptional functionality through careful engineering of their mesoscale structure. Although appropriately introduced irregularities can be advantageous, current approaches largely conform to regular structures to preserve tractability. Here, we contend that network theory, enriched with geometry and physics, provides a natural framework for designing metamaterials with controlled irregularities […]

Kavli Affiliate: Lina Necib | Summary:Self-Interacting Dark Matter (SIDM) models with large cross sections at relative velocities below $sim100,rm km , s^-1$ can be tested with dwarf galaxy observations. We analyze six dark-matter-only zoom-in $sim10^10,rm M_odot$ halos with diverse assembly histories, adopting a cross section over mass of $σ/m = 70,cm^2 , g^-1$. We find […]

Here, we present V-shape […]
Kavli Affiliate: Michael Miller | Authors: Qi Wang, Debarshi Banerjee, Erin Connolly, Claire Vanpouille-Box, Carrie Shawber, Rami Vanguri, Michael Kissner, Michael L. Miller, Darrell J. Yamashiro and Eileen P. Connolly | Summary: Background High-dose radiotherapy (RT) in cancer is immunogenic but also induces an immunosuppressive tumor microenvironment (TME) that limits the efficacy of immune checkpoint […]
Kavli Affiliate: Wei Gao| Summary:End-to-end manipulation policies, combined with web-scale pretrained Vision-Language Models (VLMs), show the promise for generalizable and dexterous robotic manipulation. However, they inherit two key limitations from 2D foundation models: 1) the reliance on 2D RGB inputs that ignores the intrinsically 3D nature of manipulation; and 2) the lack of spatial 3D […]
