Kavli Affiliate: Catherine Grant | First 5 Authors: Xiaobo Li, Shu Zhang, Catherine Grant, Matteo Guainazzi, Eric Miller | Summary: We summarize the outcome of the 10th meeting of the International Astronomical Consortium for High Energy Calibration (IACHEC), held in Beijing (People’s Republic of China) in April 2015. Over 80 scientists directly involved in the […]
Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Kiyoshi Wesley Masui, Kris Sigurdson, , , | Summary: We propose that "standard pings", brief broadband radio impulses, can be used to study the three-dimensional clustering of matter in the Universe even in the absence of redshift information. The dispersion of radio waves as they travel […]
Kavli Affiliate: Robert Goeke | First 5 Authors: Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers, Richard Hunstead, Elaine M. Sadler | Summary: Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby ($z = 0.0178$) radio galaxy associated with NGC,1534. The diffuse emission presented here is the […]
Kavli Affiliate: Rebecca A. Masterson | First 5 Authors: Niraj K. Inamdar, Richard P. Binzel, Jae Sub Hong, Branden Allen, Jonathan Grindlay | Summary: OSIRIS-REx is the third spacecraft in the NASA New Frontiers Program and is planned for launch in 2016. OSIRIS-REx will orbit the near-Earth asteroid (101955) Bennu, characterize it, and return a […]
Kavli Affiliate: Peter G. Ford | First 5 Authors: Catherine E. Grant, Mark W. Bautz, Peter G. Ford, Paul P. Plucinsky, | Summary: As the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory enters its fifteenth year of operation on orbit, it continues to perform well and produce spectacular scientific results. The response […]
Kavli Affiliate: Tom Chang | First 5 Authors: Tom Chang, Cheng-chin Wu, Marius Echim, Herve Lamy, Mark Vogelsberger | Summary: Dynamic Complexity is a phenomenon exhibited by a nonlinearly interacting system within which multitudes of different sizes of large scale coherent structures emerge, resulting in a globally nonlinear stochastic behavior vastly different from that could […]
Kavli Affiliate: Sarah N. T. Heine | First 5 Authors: Sarah N. T. Heine, Enectali Figueroa-Feliciano, John M. Rutherford, Patrick Wikus, Phil Oakley | Summary: Micro-X is a NASA-funded, sounding rocket-borne X-ray imaging spectrometer that will allow high precision measurements of velocity structure, ionization state and elemental composition of extended astrophysical systems. One of the […]
Kavli Affiliate: John Belcher | First 5 Authors: Saif Rayyan, Daniel T. Seaton, John Belcher, David E. Pritchard, Isaac Chuang | Summary: Massive Open Online Courses are an exciting new avenue for instruction and research, yet they are full of unknowns. In the Spring of 2013, MITx released its first introductory physics MOOC through the […]
Kavli Affiliate: Rebecca Masterson | First 5 Authors: Branden Allen, Jonathan Grindlay, Jaesub Hong, Richard P. Binzel, Rebecca Masterson | Summary: The OSIRIS-REx Mission was selected under the NASA New Frontiers program and is scheduled for launch in September of 2016 for a rendezvous with, and collection of a sample from the surface of asteroid […]
Kavli Affiliate: Alan Levine | First 5 Authors: Saul Rappaport, Roberto Sanchis-Ojeda, Leslie A. Rogers, Alan Levine, Joshua N. Winn | Summary: The requirement that a planet must orbit outside of its Roche limit gives a lower limit on the planet’s mean density. The minimum density depends almost entirely on the orbital period and is […]
