COOL-LAMPS VI: Lens model and New Constraints on the Properties of COOL J1241+2219, a Bright z = 5 Lyman Break Galaxy and its z = 1 Cluster Lens

Posted by dbos Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Maxwell Klein, Keren Sharon, Kate Napier, Michael D. Gladders, Gourav Khullar | Summary: We present a strong lensing analysis of COOL J1241+2219, the brightest known gravitationally lensed galaxy at $z geq 5$, based on new multi-band Hubble Space Telescope (HST) imaging data. The lensed galaxy has […]

The Mass Dependence of Hα Emission and Stellar Spindown for Fully Convective M Dwarfs

Posted by Harvard

Kavli Affiliate: David Charbonneau | First 5 Authors: Emily K. Pass, David Charbonneau, David W. Latham, Perry Berlind, Michael L. Calkins | Summary: Fully convective M dwarfs typically remain rapidly rotating and magnetically active for billions of years, followed by an abrupt and mass-dependent transition to slow rotation and quiescence. A robust understanding of this […]

Parameterizing black hole orbits for adiabatic inspiral

Posted by dbos MIT

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Scott A. Hughes, , , , | Summary: Adiabatic binary inspiral in the small mass ratio limit treats the small body as moving along a geodesic of a large Kerr black hole, with the geodesic slowly evolving due to radiative backreaction. Up to initial conditions, geodesics […]
