A Tale of Two Transition Disks: ALMA long-baseline observations of ISO-Oph 2 reveal two closely packed non-axisymmetric rings and a $sim$2 au cavity

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Camilo González-Ruilova, Lucas A. Cieza, Antonio S. Hales, Sebastián Pérez, Alice Zurlo | Summary: ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M$_{dust}$ $sim$40 M$_{oplus}$) ring-like disk with a dust cavity $sim$50 au in radius and the secondary […]

Searching for New Interactions at Sub-micron Scale Using the Mossbauer Effect

Posted by klaurent Stanford

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Giorgio Gratta, David E. Kaplan, Surjeet Rajendran, , | Summary: A new technique to search for new scalar and tensor interactions at the sub-micrometer scale is presented. The technique relies on small shifts of nuclear gamma lines produced by the coupling between matter and the nuclei in […]

From haloes to galaxies — II. The fundamental relations in star formation and quenching

Posted by klaurent Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci | Summary: Star formation and quenching are two of the most important processes in galaxy formation and evolution. We explore in the local Universe the interrelationships among key integrated galaxy properties, including stellar mass $M_*$, star […]
