Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Dillon Brout, Richard Kessler, Dan Scolnic, Lisa Lu | Summary: Improving the use of Type Ia supernovae (SNIa) as standard candles requires a better approach to incorporate the relationship between SNIa and the properties of their host galaxies. Using a spectroscopically-confirmed sample of $sim$1600 SNIa, […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Giuseppe Cataldo, Peter Ade, Christopher Anderson, Alyssa Barlis, Emily Barrentine | Summary: The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a balloon-borne far-infrared telescope that will survey star formation history over cosmological time scales to improve our understanding of why the star formation rate declined at […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Nickolay Y. Gnedin, , , | Summary: The matter density field at $zsim 6$ is very challenging to probe. One of the traditional probes of the low density IGM that works successfully at lower redshifts is the Lyman-alpha forest in quasar spectra. However, at […]
Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Joseph E. Golec, Jeffrey J. McMahon, Aamir M. Ali, Grace E. Chesmore, Leah Cooperrider | Summary: The Simons Observatory (SO) will be a cosmic microwave background (CMB) survey experiment with three small-aperture telescopes and one large-aperture telescope, which will observe from the Atacama Desert in Chile. […]
Kavli Affiliate: Cosmin Deaconu | First 5 Authors: Majd Ghrear, Sven E. Vahsen, Cosmin Deaconu, , | Summary: Directional detection of nuclear recoils is broadly desirable in nuclear and particle physics. At low recoil energies, this capability may be used to confirm the cosmological origin of a dark matter signal, to penetrate the so-called neutrino […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Thomas Essinger-Hileman, Trevor Oxholm, Gage Siebert, Peter Ade, Christopher Anderson | Summary: This work describes the optical design of the EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM). EXCLAIM is a balloon-borne telescope that will measure integrated line emission from carbon monoxide (CO) at redshifts z < 1 […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Thomas Essinger-Hileman, Trevor Oxholm, Gage Siebert, Alyssa Barlis, Emily M. Barrentine | Summary: This work describes the design and implementation of optics for EXCLAIM, the EXperiment for Cryogenic Large-Aperture Intensity Mapping. EXCLAIM is a balloon-borne telescope that will measure integrated line emission from carbon monoxide (CO) at […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Thomas Essinger-Hileman, Danny Chmaytelli, Trevor Oxholm, Tatsat Parekh, Gage Siebert | Summary: This work describes the design and implementation of optics for EXCLAIM, the EXperiment for Cryogenic Large-Aperture Intensity Mapping. EXCLAIM is a balloon-borne telescope that will measure integrated line emission from carbon monoxide (CO) at redshifts […]
Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Jonathan W. Richardson, Ohkyung Kwon, H. Richard Gustafson, Craig Hogan, Brittany L. Kamai | Summary: Precision measurements are reported of the cross-spectrum of rotationally-induced differential position displacements in a pair of colocated 39 m long, high power Michelson interferometers. One arm of each interferometer is bent […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: , , , , | Summary: Observations of the $gamma$-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy average. We explore the […]
