Machine learning synthetic spectra for probabilistic redshift estimation: SYTH-Z

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Nesar Ramachandra, Jonás Chaves-Montero, Alex Alarcon, Arindam Fadikar, Salman Habib | Summary: Photometric redshift estimation algorithms are often based on representative data from observational campaigns. Data-driven methods of this type are subject to a number of potential deficiencies, such as sample bias and incompleteness. Motivated by these […]

A NICER look at thermonuclear X-ray bursts from Aql X-1

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Tolga Guver, Tugba Boztepe, David R. Ballantyne, Z. Funda Bostanci, Peter Bult | Summary: We present spectral and temporal properties of all the thermonuclear X-ray bursts observed from Aql X-1 by the Neutron Star Interior and Composition Explorer (NICER) between 2017 July and 2021 April. This is […]

Broadband solenoidal haloscope for terahertz axion detection

Kavli Affiliate: Clarence Chang | First 5 Authors: Jesse Liu, Kristin Dona, Gabe Hoshino, Stefan Knirck, Noah Kurinsky | Summary: We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program. This haloscope plans to search for bosonic dark matter across the [10$^{-3}$, 1] eV ([0.24, 240] THz) mass range. BREAD […]

TIC 5724661: A Long-Period Binary with a Pulsating sdB Star and $δ$ Scuti Variable

Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Saul Rappaport, Lorne Nelson, Donald W. Kurtz, George Dufresne | Summary: Using the novel TESS 20-sec cadence data, we have discovered an unusual combination of pulsating stars in what we infer to be a binary system. The primary is a standard $delta$ Scuti star with […]

Nonrelativistic CFTs at Large Charge: Casimir Energy and Logarithmic Enhancements

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Domenico Orlando, Vito Pellizzani, Susanne Reffert, Ian Swanson | Summary: The unitary Fermi gas, by virtue of its description as a nonrelativistic conformal field theory, has proven an interesting system by which the quantum properties of CFT can be held to experimental verification. Here, we […]

TOI-2109b: An Ultrahot Gas Giant on a 16 hr Orbit

Kavli Affiliate: George R. Ricker | First 5 Authors: Ian Wong, Avi Shporer, George Zhou, Daniel Kitzmann, Thaddeus D. Komacek | Summary: We report the discovery of an ultrahot Jupiter with an extremely short orbital period of $0.67247414,pm,0.00000028$ days ($sim$16 hr). The $1.347 pm 0.047$ $R_{rm Jup}$ planet, initially identified by the Transiting Exoplanet Survey […]

Magnetospheric curvature radiation by bunches as emission mechanism for repeating fast radio bursts

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Yuan-Pei Yang, Chen-Hui Niu, Renxin Xu, Bing Zhang | Summary: Coherent curvature radiation as the radiation mechanism for fast radio bursts (FRBs) has been discussed since FRBs were discovered. We study the spectral and polarization properties of repeating FRBs within the framework of coherent curvature […]

HSC Year 1 cosmology results with the minimal bias method: HSC$times$BOSS galaxy-galaxy weak lensing and BOSS galaxy clustering

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Sunao Sugiyama, Masahiro Takada, Hironao Miyatake, Takahiro Nishimichi, Masato Shirasaki | Summary: We present cosmological parameter constraints from a blinded joint analysis of galaxy-galaxy weak lensing, $Delta!Sigma(R)$, and projected correlation function, $w_mathrm{p}(R)$, measured from the first-year HSC (HSC-Y1) data and SDSS spectroscopic galaxies over $0.15<z<0.7$. We use […]
