High redshift JWST predictions from IllustrisTNG: III. Infrared luminosity functions, obscured star formation and dust temperature of high-redshift galaxies

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Dylan Nelson, Sandro Tacchella, Lars Hernquist | Summary: We post-process galaxies in the IllustrisTNG simulations with SKIRT radiative transfer calculations to make predictions for the rest-frame near-infrared (NIR) and far-infrared (FIR) properties of galaxies at $zgeq 4$. The rest-frame $K$- and $z$-band galaxy […]

Via Machinae: Searching for Stellar Streams using Unsupervised Machine Learning

Posted by klaurent MIT

Kavli Affiliate: Lina Necib | First 5 Authors: David Shih, Matthew R. Buckley, Lina Necib, John Tamanas, | Summary: We develop a new machine learning algorithm, Via Machinae, to identify cold stellar streams in data from the Gaia telescope. Via Machinae is based on ANODE, a general method that uses conditional density estimation and sideband […]

Search for $B^{+}to K^{+}νbarν$ decays using an inclusive tagging method at Belle II

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, P. Ahlburg | Summary: A search for the flavor-changing neutral-current decay $B^{+}to K^{+}nubar{nu}$ is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The results are based on a data sample corresponding to an […]

Neutral vs Ion Linewidths in Barnard 5: Evidence for Penetration by MHD Waves

Posted by klaurent Stanford

Kavli Affiliate: Sarah E. Church | First 5 Authors: Jaime E. Pineda, Anika Schmiedeke, Paola Caselli, Steven W. Stahler, David T. Frayer | Summary: Dense cores are the final place where turbulence is dissipated. It has been proposed from theoretical arguments that the non-thermal velocity dispersion should be narrower both for molecular ions (compared to […]

Effects of model incompleteness on the drift-scan calibration of radio telescopes

Posted by klaurent MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman, Nivedita Mahesh, Steven G. Murray | Summary: Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both interferometric and global signal experiments, systematic […]

TOI-1431b/MASCARA-5b: A Highly Irradiated Ultra-Hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars

Posted by klaurent MIT

Kavli Affiliate: Alan M. Levine | First 5 Authors: Brett Christopher Addison, Emil Knudstrup, Ian Wong, Guillaume Hebrard, Patrick Dorval | Summary: We present the discovery of a highly irradiated and moderately inflated ultra-hot Jupiter, TOI-1431b/MASCARA-5b (HD 201033b), first detected by NASA’s Transiting Exoplanet Survey Satellite mission (TESS) and the Multi-site All-Sky CAmeRA (MASCARA). The […]

Spontaneous tilt of single-clamped thermal elastic sheets

Posted by klaurent UCSB

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Zhitao Chen, Duanduan Wan, Mark J. Bowick, , | Summary: Very thin elastic sheets, even at zero temperature, exhibit nonlinear elastic response by virtue of their dominant bending modes. Their behavior is even richer at finite temperature. Here we use molecular dynamics (MD) to study the […]

X-ray polarimetry of the Crab nebula with PolarLight: polarization recovery after the glitch and a secular position angle variation

Posted by klaurent Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Xiangyun Long, Hua Feng, Hong Li, Jiahuan Zhu, Qiong Wu | Summary: We report follow-up observations of the Crab nebula with the PolarLight X-ray polarimeter, which revealed a possible variation in polarization associated with a pulsar glitch in 2019. The new observations confirm that the polarization has […]

Hermeian haloes: Field haloes that interacted with both the Milky Way and M31

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Oliver Newton, Noam I. Libeskind, Alexander Knebe, Miguel A. Sánchez-Conde, Jenny G. Sorce | Summary: The Local Group is a unique environment in which to study the astrophysics of galaxy formation. The proximity of the Milky Way and M31 enhances the frequency of interactions of the low-mass […]

Multiplet supercurrent in Josephson tunneling circuits

Posted by klaurent Delft

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: André Melo, Valla Fatemi, Anton R. Akhmerov, , | Summary: The multi-terminal Josephson effect allows DC supercurrent to flow at finite commensurate voltages. Existing proposals to realize this effect rely on nonlocal Andreev processes in superconductor-normal-superconductor junctions. However, this approach requires precise control over microscopic states […]
