SED Analysis of 13 Spectroscopically Confirmed Galaxies at z$simeq$6 to Constrain UV-Slope, Model Dust Attenuation and Escape Fractions

Kavli Affiliate: Linhua Jiang | First 5 Authors: Junehyoung Jeon, Rogier Windhorst, Seth H. Cohen, Rolf A. Jansen, Brent M. Smith | Summary: The reionization of the hydrogen in the Universe is thought to have completed by redshift $zsimeq5.5-6$. To probe this era, galaxy observations in the Subaru Deep Field (SDF) have identified more than […]

Re-detection and a Possible Time Variation of Soft X-ray Polarisation from the Crab

Kavli Affiliate: Renxin Xu | First 5 Authors: Hua Feng, Hong Li, Xiangyun Long, Ronaldo Bellazzini, Enrico Costa | Summary: The Crab nebula is so far the only celestial object with a statistically significant detection in soft x-ray polarimetry, a window that has not been explored in astronomy since the 1970s. However, soft x-ray polarimetry […]

On the Circular Polarisation of Repeating Fast Radio Bursts

Kavli Affiliate: Renxin Xu | First 5 Authors: Shi Dai, Jiguang Lu, Chen Wang, Weiyang Wang, Renxin Xu | Summary: Fast spinning (e.g., sub-second) neutron star with ultra-strong magnetic fields (or so-called magnetar) is one of the promising origins of repeating fast radio bursts (FRBs). Here we discuss circularly polarised emissions produced by propagation effects […]

Pulsar glitches in a strangeon star model. II. The activity

Kavli Affiliate: Renxin Xu | First 5 Authors: Weihua Wang, Xiaoyu Lai, Enping Zhou, Jiguang Lu, Xiaoping Zheng | Summary: Glitch is supposed to be a useful probe into pulsar’s interior, but the underlying physics remains puzzling. The glitch activity may reflect a lower limit of the crustal moment of inertia in conventional neutron star […]

Exciting modes due to the aberration of gravitational waves: Measurability for extreme-mass-ratio inspirals

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Alejandro Torres-Orjuela, Pau Amaro Seoane, Zeyuan Xuan, Alvin J. K. Chua, María J. B. Rosell | Summary: Gravitational waves from a source moving relative to us can suffer from special-relativistic effects such as aberration. The required velocities for these to be significant are on the order […]

The Dust-to-Gas Ratio and the Role of Radiation Pressure in Luminous, Obscured Quasars

Kavli Affiliate: Claudio Ricci | First 5 Authors: Hyunsung D. Jun, Roberto J. Assef, Christopher M. Carroll, Ryan C. Hickox, Yonghwi Kim | Summary: The absence of high Eddington ratio, obscured Active Galactic Nuclei (AGN) in local ($zlesssim0.1$) samples of moderate luminosity AGN has generally been explained to result from radiation pressure on the dusty […]

Curvature conditions for spatial isotropy

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Kostas Tzanavaris, Pau Amaro Seoane, , , | Summary: In the context of mathematical cosmology, the study of necessary and sufficient conditions for a semi-Riemannian manifold to be a (generalised) Robertson-Walker space-time is important. In particular, it is a requirement for the development of initial data […]

Assessing Classifier Fairness with Collider Bias

Kavli Affiliate: Ke Wang | First 5 Authors: Zhenlong Xu, Ziqi Xu, Jixue Liu, Debo Cheng, Jiuyong Li | Summary: The increasing application of machine learning techniques in everyday decision-making processes has brought concerns about the fairness of algorithmic decision-making. This paper concerns the problem of collider bias which produces spurious associations in fairness assessment […]

A Tale of Two Transition Disks: ALMA long-baseline observations of ISO-Oph 2 reveal two closely packed non-axisymmetric rings and a $sim$2 au cavity

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Camilo González-Ruilova, Lucas A. Cieza, Antonio S. Hales, Sebastián Pérez, Alice Zurlo | Summary: ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M$_{dust}$ $sim$40 M$_{oplus}$) ring-like disk with a dust cavity $sim$50 au in radius and the secondary […]
