Modeling the wavelength dependence of pixel response non-uniformity of a CCD sensor

Kavli Affiliate: Hu Zhan | First 5 Authors: Zun Luo, Wei Du, Baocun Chen, Xianmin Meng, Hu Zhan | Summary: Precision measurements in astronomy require stringent control of systematics such as those arising from imperfect correction of sensor effects. In this work, we develop a parametric method to model the wavelength dependence of pixel response […]

On the Scarcity of Dense Cores ($n>10^{5}$ cm$^{-3}$) in High Latitude Planck Galactic Cold Clumps

Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Tie Liu, David Eden, Xunchuan Liu | Summary: High-latitude ($|b|>30^{circ}$) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Planck […]

Luminosity Functions of the Host Galaxies of Supernova

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Zhuoxi Liang, Nao Suzuki, Mamoru Doi, Masayuki Tanaka, Naoki Yasuda | Summary: We present the luminosity functions and stellar mass functions of supernova (SN) host galaxies and test if they differ from the functions of normal field galaxies. We utilize homogeneous samples consisting of 273 SNe Ia […]

An experimental census of retrons for DNA production and genome editing

Kavli Affiliate: Seth Shipman | Authors: Asim G. Khan, Matías Rojas-Montero, Alejandro González-Delgado, Santiago C. Lopez, Rebecca F. Fang and Seth L. Shipman | Summary: Abstract Retrons are bacterial immune systems that use reverse transcribed DNA as a detector of phage infection. They are also increasingly deployed as a component of biotechnology. For genome editing, […]

Geometry of anisotropic contextual interactions in the visual cortex places fundamental limits on spatial vision

Kavli Affiliate: Anirvan Nandy | Authors: Mitchell P. Morton, Sachira Denagamage, Nyomi V. Hudson and Anirvan S. Nandy | Summary: Crowding, the impaired ability to accurately recognize a target stimulus among distractors, is a major bottleneck in visual perception. The spatial configuration of distractors in relation to the target profoundly influences perceptual fidelity. Notably, when […]

Intensive Swift and LCO monitoring of PG 1302$-$102: AGN disk reverberation mapping of a supermassive black hole binary candidate

Kavli Affiliate: Erin Kara | First 5 Authors: Tingting Liu, Rick Edelson, Juan V. Hernández Santisteban, Erin Kara, John Montano | Summary: We present an intensive multiwavelength monitoring campaign of the quasar PG 1302$-$102 with Swift and the Las Cumbres Observatory network telescopes. At $zsim0.3$, it tests the limits of the reverberation mapping (RM) technique […]

Small-scale radio jets and tidal disruption events: A theory of high-luminosity compact symmetric objects

Kavli Affiliate: Roger D. Blandford | First 5 Authors: Andrew G. Sullivan, Roger D. Blandford, Mitchell C. Begelman, Mark Birkinshaw, Anthony C. S. Readhead | Summary: Double lobe radio sources associated with active galactic nuclei represent one of the longest studied groups in radio astronomy. A particular sub-group of double radio sources comprises the compact […]
