Relative alignment between gas structures and magnetic field in Orion A at different scales using different molecular gas tracers

Kavli Affiliate: Ke Wang | First 5 Authors: Wenyu Jiao, Ke Wang, Fengwei Xu, Chao Wang, Henrik Beuther | Summary: Context: Magnetic fields can play crucial roles in high-mass star formation. Nonetheless, the significance of magnetic fields at various scales and their relationship with gas structures is largely overlooked. Aims: Our goal is to examine […]

Galaxies lensing quadruply imaged quasars lie close to the centers of their lensing potentials

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: In modeling the potentials of quadruply lensed quasars, investigators often employ models for the stellar surface brightness profile of the lensing galaxy for the sole purpose of eliminating its contamination of the light from the quasar images […]

Witt’s hyperbola is both predicted and observed to pass close to the lensing galaxies in quadruple quasars

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: When a rectangular hyperbola is constructed from the image positions of a quadruply lensed quasar, as proposed by Witt (1996), it passes very close to the the lensing galaxy. The median measured perpendicular offset between the observed […]

AGN feedback in the Local Universe: multiphase outflow of the Seyfert galaxy NGC 5506

Kavli Affiliate: Claudio Ricci | First 5 Authors: Federico Esposito, Almudena Alonso-Herrero, Santiago García-Burillo, Viviana Casasola, Françoise Combes | Summary: We present new optical GTC/MEGARA seeing-limited (0.9") integral-field observations of NGC 5506, together with ALMA observations of the CO(3-2) transition at a 0.2" (25 pc) resolution. NGC 5506 is a luminous (bolometric luminosity of $sim […]

A dormant, overmassive black hole in the early Universe

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Roberto Maiolino, William M. Baker, Sandro Tacchella, Jan Scholtz | Summary: Recent observations have found a large number of supermassive black holes already in place in the first few hundred million years after Big Bang. The channels of formation and growth of these early, massive […]

Impact of baryonic feedback on HSC Y1 weak lensing non-Gaussian statistics

Kavli Affiliate: Jia Liu | First 5 Authors: Daniela Grandón, Gabriela A. Marques, Leander Thiele, Sihao Cheng, Masato Shirasaki | Summary: Baryonic feedback is a major systematic in weak lensing cosmology. Its most studied effect is the suppression of the lensing power spectrum, a second-order statistic, on small scales. Motivated by the growing interest in […]

The double-peaked type I X-ray bursts with different mass accretion rate and fuel composition

Kavli Affiliate: Renxin Xu | First 5 Authors: Liyu Song, Helei Liu, Chunhua Zhu, Guoqing Zhen, Guoliang Lv | Summary: Using the MESA code, we have carried out a detailed survey of the available parameter space for the double-peaked type I X-ray bursts. We find that the double-peaked structure appears at mass accretion rate $dot{M}$ […]

ALMA Spectral Survey of An eruptive Young star, V883 Ori (ASSAY): I. What triggered the current episode of eruption?

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Jeong-Eun Lee, Chul-Hwan Kim, Seokho Lee, Giseon Baek, Hyeong-Sik Yun | Summary: An unbiased spectral survey of V883 Ori, an eruptive young star, was carried out with the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6. The detected line emission from various molecules reveals morphological/kinematical features […]
