Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, , , , | Summary: An optimal estimate for Stokes parameters is derived for the situation in X-ray astronomy where the instrument has a modulation factor that varies significantly with energy but the signals are very weak or mildly polarized. For such sources, […]
Kavli Affiliate: David A. Principe | First 5 Authors: Lucas A. Cieza, Camilo González-Ruilova, Antonio S. Hales, Paola Pinilla, Dary Ruíz-Rodríguez | Summary: We present 1.3 mm continuum ALMA long-baseline observations at 3-5 au resolution of 10 of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project. We identify a total of […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Yuhan Yao, S. R. Kulkarni, K. C. Gendreau, Gaurava K. Jaisawal, Teruaki Enoto | Summary: Here, we present MAXI, SWIFT, NICER, NuSTAR and Chandra observations of the X-ray transient AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234). From spectral and timing analyses we classify it as a Galactic low-mass […]
Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Hans Moritz Günther, Ralf K. Heilmann, , , | Summary: Lynx is one of four large-mission concept studies for NASA’s 2020 Decadal survey. The design reference mission includes an X-ray grating spectrometer (XGS) based on critical-angle transmission (CAT) gratings. In the past we studied different grating […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Hans Moritz Günther, Herman L. Marshall, Alan Garner, , | Summary: X-ray polarimetry is still largely uncharted territory. With the upcoming launch of IXPE, we will learn a lot more about X-ray polarization at energies above 2 keV, but so far no current or accepted mission […]
Kavli Affiliate: Michael Zucker | First 5 Authors: Weixiang Jin, Michael Zucker, Arnd Pralle, , | Summary: Some anesthetics bind and potentiate gamma-aminobutyric-acid-type receptors, but no universal mechanism for general anesthesia is known. Furthermore, often encountered complications such as anesthesia induced amnesia are not understood. General anesthetics are hydrophobic molecules easily dissolving into lipid bilayers. […]
Kavli Affiliate: Eric Miller | First 5 Authors: Ruijie Jiang, Julia Gouvea, David Hammer, Eric Miller, Shuchin Aeron | Summary: Qualitative analysis of verbal data is of central importance in the learning sciences. It is labor-intensive and time-consuming, however, which limits the amount of data researchers can include in studies. This work is a step […]
Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: George Zhou, Samuel N. Quinn, Jonathan Irwin, Chelsea X. Huang, Karen A. Collins | Summary: Planets around young stars trace the early evolution of planetary systems. We report the discovery and validation of two planetary systems with ages $lesssim 300$ Myr from observations by the Transiting […]
Kavli Affiliate: George Ricker | First 5 Authors: Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang, Tianjun Gan, Mykhaylo Plotnykov | Summary: $Kepler$ revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they made of, and do […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Shifan Zuo, Jixia Li, Yichao Li, Das Santanu, Albert Stebbins | Summary: The Tianlai project is a 21cm intensity mapping experiment aimed at detecting dark energy by measuring the baryon acoustic oscillation (BAO) features in the large scale structure power spectrum. This experiment provides an opportunity […]
