High-speed X-ray imaging spectroscopy system with Zynq SoC for solar observations

Posted by klaurent Tokyo

Kavli Affiliate: Tadashi Orita | First 5 Authors: Shin-nosuke Ishikawa, Tadayuki Takahashi, Shin Watanabe, Noriyuki Narukage, Satoshi Miyazaki | Summary: We have developed a system combining a back-illuminated Complementary-Metal-Oxide-Semiconductor (CMOS) imaging sensor and Xilinx Zynq System-on-Chip (SoC) device for a soft X-ray (0.5-10 keV) imaging spectroscopy observation of the Sun to investigate the dynamics of […]

The Sunburst Arc: Direct Lyman α escape observed in the brightest known lensed galaxy

Posted by klaurent MIT

Kavli Affiliate: Robert Simcoe | First 5 Authors: T. Emil Rivera-Thorsen, Håkon Dahle, Max Gronke, Matthew Bayliss, Jane Rigby | Summary: We present rest-frame ultraviolet and optical spectroscopy of the brightest lensed galaxy yet discovered, at redshift z = 2.4. This source reveals a characteristic, triple-peaked Lyman {alpha} profile which has been predicted by various […]

Scientific Synergy Between LSST and Euclid

Posted by klaurent Stanford

Kavli Affiliate: Steven Kahn | First 5 Authors: Jason Rhodes, Robert C. Nichol, Éric Aubourg, Rachel Bean, Dominique Boutigny | Summary: Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high cadence, deep, wide-field optical photometry from LSST with high […]

Hamiltonian approach to 2nd order gauge invariant cosmological perturbations

Posted by klaurent Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Misao Sasaki, , , | Summary: In view of growing interest in tensor modes and their possible detection, we clarify the definition of tensor modes up to 2nd order in perturbation theory within the Hamiltonian formalism. Like in gauge theory, in cosmology the Hamiltonian is […]

Time-symmetric integration in astrophysics

Posted by klaurent MIT

Kavli Affiliate: Edmund Bertschinger | First 5 Authors: David M. Hernandez, Edmund Bertschinger, , , | Summary: Calculating the long term solution of ordinary differential equations, such as those of the $N$-body problem, is central to understanding a wide range of dynamics in astrophysics, from galaxy formation to planetary chaos. Because generally no analytic solution […]

Molecular gas in three z~7 quasar host galaxies

Posted by klaurent Cambridge

Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Carl Ferkinhoff, Axel Weiss | Summary: We present ALMA band 3 observations of the CO(6-5), CO(7-6), and [CI] 369micron emission lines in three of the highest redshift quasar host galaxies at 6.6<z<6.9. These measurements constitute the highest-redshift CO detections to […]

Ring objects in the equivariant derived Satake category arising from Coulomb branches (with an appendix by Gus Lonergan)

Posted by dbos Tokyo

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: This is the second companion paper of arXiv:1601.03586. We consider the morphism from the variety of triples introduced in arXiv:1601.03586 to the affine Grassmannian. The direct image of the dualizing complex is a ring object in the equivariant […]

Two- and Three-Dimensional Probes of Parity in Primordial Gravity Waves

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Kiyoshi Wesley Masui, Ue-Li Pen, Neil Turok, , | Summary: We show that three-dimensional information is critical to discerning the effects of parity violation in the primordial gravity-wave background. If present, helical gravity waves induce parity-violating correlations in the cosmic microwave background (CMB) between parity-odd polarization […]

The compact, ~1 kpc host galaxy of a quasar at z=7.1

Posted by klaurent Cambridge

Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Eduardo Banados, Jacqueline Hodge | Summary: We present ALMA observations of the [CII] fine structure line and the underlying far-infrared (FIR) dust continuum emission in J1120+0641, the most distant quasar currently known (z=7.1). We also present observations targeting the CO(2-1), […]
