The Discovery of Little Red Dots in the Local Universe: Signatures of Cool Gas Envelopes

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | Summary:JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0.1$-$0.2$, initially selected from the SDSS database, with follow-up optical/near-IR spectroscopy and photometry. They exhibit properties fully consistent with those of high-redshift […]

Modeling Atmospheric Alteration on Titan: Hydrodynamics and Shock-Induced Chemistry of Meteoroid Entry

Posted by klaurent Stanford

Kavli Affiliate: Laura Schaefer | Summary:Meteoroid entry into planetary atmospheres generates bow shocks, resulting in high-temperature gas conditions that drive chemical reactions. In this paper, we perform three-dimensional hydrodynamic simulations of meteoroid entry using the Athena++ code, coupled with chemistry calculations via Cantera to model the non-equilibrium chemistry triggered by atmospheric entry. Our aerodynamical simulations […]

Attosecond charge transfer in atomic-resolution scanning tunnelling microscopy

Posted by klaurent Berkeley

Kavli Affiliate: Carlos Bustamante | Summary:Electrons in atoms and molecules move on attosecond time scales. Deciphering their quantum dynamics in space and time calls for high-resolution microscopy at this speed. While scanning tunnelling microscopy (STM) driven with terahertz pulses has visualized sub-picosecond motion of single atoms, the advent of attosecond light pulses has provided access […]
