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 […]

The Eccentric and Accelerating Stellar Binary Black Hole Mergers in Galactic Nuclei: Observing in Ground and Space Gravitational Wave Observatories

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Fupeng Zhang, Xian Chen, Lijing Shao, Kohei Inayoshi, | Summary: We study the stellar binary black holes (BBHs) inspiralling/merging in galactic nuclei based on our numerical method GNC. We find that $3-40%$ of all new born BBHs will finally merge due to various dynamical effects. In a […]
