BICEP / Keck XIII: Improved Constraints on Primordial Gravitational Waves using Planck, WMAP, and BICEP/Keck Observations through the 2018 Observing Season

Kavli Affiliate: C. L. Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We present results from an analysis of all data taken by the BICEP2, Keck Array and BICEP3 CMB polarization experiments up to and including the 2018 observing season. We add additional Keck Array […]

BICEP / Keck XV: The BICEP3 CMB Polarimeter and the First Three Year Data Set

Kavli Affiliate: C. L. Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We report on the design and performance of the BICEP3 instrument and its first three-year data set collected from 2016 to 2018. BICEP3 is a 52cm aperture, refracting telescope designed to observe the […]

Core-collapse, evaporation and tidal effects: the life story of a self-interacting dark matter subhalo

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du, Andrew Benson, Stacy Kim | Summary: Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter (DM) halo density profiles, from low-density cores to high-density core-collapsed cusps. The possibility of the growth of high central density […]

Anomalies of Cosmic Anisotropy from Holographic Universality of Great-Circle Variance

Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Nathaniel Selub, Frederick Wehlen, Craig Hogan, Stephan S. Meyer, | Summary: We examine all-sky cosmic microwave background (CMB) temperature maps on large angular scales to test consistency with a hypothesized cosmological symmetry: a universal variance of primordial curvature perturbations on great circles. This symmetry is not […]

The KLEVER survey: Nitrogen abundances at $zsim$2 and probing the existence of a fundamental nitrogen relation

Kavli Affiliate: Yingjie Peng | First 5 Authors: Connor Hayden-Pawson, Mirko Curti, Roberto Maiolino, Michele Cirasuolo, Francesco Belfiore | Summary: We present a comparison of the nitrogen-to-oxygen ratio (N/O) in 37 high-redshift galaxies at $zsim$2 taken from the KMOS Lensed Emission Lines and VElocity Review (KLEVER) Survey with a comparison sample of local galaxies, taken […]

The HASHTAG project: The First Submillimeter Images of the Andromeda Galaxy from the Ground

Kavli Affiliate: Yingjie Peng | First 5 Authors: Matthew W. L. Smith, Stephen A. Eales, Thomas G. Williams, Bumhyun Lee, Zongnan Li | Summary: Observing nearby galaxies with submillimeter telescopes on the ground has two major challenges. First, the brightness is significantly reduced at long submillimeter wavelengths compared to the brightness at the peak of […]

Cosmological constraints without fingers of God

Kavli Affiliate: Masahiro Takada | First 5 Authors: Mikhail M. Ivanov, Oliver H. E. Philcox, Marko Simonović, Matias Zaldarriaga, Takahiro Nishimichi | Summary: Non-linear redshift-space distortions ("fingers of God") are challenging to model analytically, a fact that limits the applicability of perturbation theory in redshift space as compared to real space. We show how this […]

A Large Diameter Millimeter-Wave Low-Pass Filter Made of Alumina with Laser Ablated Anti-Reflection Coating

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Ryota Takaku, Qi Wen, Scott Cray, Mark Devlin, Simon Dicker | Summary: We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) made with laser-ablated sub-wavelength structures (SWS). The filter has been integrated into and is operating with the MUSTANG2 […]

Investigating the existence of gravitomagnetic monopole in M87*

Kavli Affiliate: Qingjuan Yu | First 5 Authors: M. Ghasemi-Nodehi, Chandrachur Chakraborty, Qingjuan Yu, Youjun Lu, | Summary: We examine the possibility for the existence of gravitomagnetic monopole ($n_*$) in M87* by using the results obtained from its first Event Horizon Telescope image. By numerically deducing the shadow sizes in Kerr-Taub-NUT (KTN) spacetime, we show […]
