Gradient estimates for positive eigenfunctions of $ \mathcal{L} $-operator on conformal solitons and its applications
We prove a local gradient estimate for positive eigenfunctions of $ \mathcal{L} $-operator on conformal solitons given by a general conformal vector field. As an application, we obtain a Liouville type theorem for $ \mathcal{L} u = 0 $, which improves the one of Li--Sun (Acta Math. Sin. (Engl. Ser.), 37(11): 1768--1782, 2021.). We also consider applications where manifolds are special conformal solitons. Especially in the case of self-shrinkers, a better Liouville type theorem is obtained.

Model-theoretic frameworks for Nonstandard Analysis depend on the existence of nonprincipal ultrafilters, a strong form of the Axiom of Choice (AC). Hrbacek and Katz, APAL 72 (2021) formulate axiomatic nonstandard set theories SPOT and SCOT that are conservative extensions of respectively ZF and ZF + ADC (the Axiom of Dependent Choice), and in which a significant part of Nonstandard Analysis can be developed.

The Penrose Inequality for Metrics with Singular Sets
We study the Penrose inequality and its rigidity for metrics with singular sets. Our result could be viewed as a complement of Theorem 1.1 of Lu and Miao (J. Funct. Anal. 281, 2021) and Theorem 1.2 of Shi, Wang and Yu (Math. Z. 291, 2019), in which they assume the singular set is a hypersurface and assume an additional condition on the mean curvature. As a complement, this paper study the case of singular set of dimensional less than n-1, without any additional conditions.

Maximal multiplicity of Laplacian eigenvalues in negatively curved surfaces
In this work, we obtain the first upper bound on the multiplicity of Laplacian eigenvalues for negatively curved surfaces which is sublinear in the genus g. Our proof relies on a trace argument for the heat kernel, and on the idea of leveraging an r-net in the surface to control this trace. This last idea was introduced in [Jiang-Tidor-Yao-Zhang-Zhao, 2021] for similar spectral purposes in the context of graphs of bounded degree. Our method is robust enough to also yield an upper bound on the `…

Unveiling Luminous Ly$α$ Emitters at $z\approx6$ through JWST/NIRCam Imaging in the COSMOS Field
We study a sample of 14 spectroscopically confirmed Ly$α$ Emitters (LAEs) in the late era of reionization (at redshift $z\approx6$) based on the JWST/NIRCam imaging dataset. These LAEs with high Ly$α$ luminosity of $L$(Ly$α$) $\sim10^{42.4-43.4}$ erg s$^{-1}$ have been covered by the (ongoing) COSMOS-Web survey (Kartaltepe et al. 2021; Casey et al. 2022) over $0.28$ deg$^2$ in four NIRCam bands (F115W, F150W, F277W, and F444W). With JWST imaging, we determine the UV continua with $M_{\rm UV}…

The ultimate upper bound on the injectivity radius of the Stiefel manifold
We exhibit conjugate points on the Stiefel manifold endowed with any member of the family of Riemannian metrics introduced by Hüper et al. (2021). This family contains the well-known canonical and Euclidean metrics. An upper bound on the injectivity radius of the Stiefel manifold in the considered metric is then obtained as the minimum between the length of the geodesic along which the points are conjugate and the length of certain geodesic loops. Numerical experiments support the conjecture t…

XMM-Newton --NuSTAR monitoring campaign of the Seyfert 1 galaxy IC 4329A
We present the results of a joint {\it XMM-Newton} and {\it NuSTAR} campaign on the active galactic nucleus (AGN) IC 4329A, consisting of 9 $\times$ 20 ks {\it XMM-Newton} observations, and 5 $\times$ 20 ks {\it NuSTAR} observations within nine days, performed in August 2021. Within each observation, the AGN is not very variable, with the fractional variability never exceeding 5%. Flux variations are observed between the different observations, on timescales of days, with a 30% ratio between th…

Three big names the Philadelphia Eagles should avoid in free agency
With more than $40M available under the NFL's new salary cap, the Eagles can afford to add some big-name talent to their 2024 roster. Just not these guys. RB Austin Ekeler Ekeler’s Chargers career got off to a slow start after he went undrafted out of Western Colorado in 2017. Ekeler tallied just 1,901 yards and nine touchdowns in his first four seasons. But things changed in 2021 when he ran for 911 yards and 12 touchdowns, followed by 915 yards and 13 scores in 2022. Unfortunately, Ekeler�…

Time for your daily dose of #RustLang complaints. Yep, the ecosystem is doing great.
#UV depends on tokio-tar library. Tokio-tar is broken on #PowerPC, doesn't have a bug tracker (!) and seems to be quite dead, with a bunch of PRs ignored since 2022 (last activity mid-2023). Nevertheless, I've filed a PR to fix PowerPC, with little hope that it'll be merged, released and that we could get UV working on PowerPC.
On top of that, it seems that tokio-tar was forked in early 2021 from async-tar. It doesn't seem to have synced the few commits from 2021, and async-tar is dead since late 2021. But at least it has a bug tracker to keep track of how dead it is.
Rewriting stuff in Rust is great. Maintaining it afterwards for the sake of reverse dependencies isn't.

A heuristic account of the radiation by the superluminally moving current sheet in the magnetosphere of a neutron star
Results of the mathematical treatment of the radiation by the superluminally moving current sheet in the magnetosphere of a neutron star, which was presented in Ardavan (2021, {\it MNRAS}, {\bf 507}, 4530), are explained here in more transparent physical terms with the aid of illustrations. Not only do these results provide an all-encompassing explanation for the salient features of the radiation received from pulsars (its brightness temperature, polarization, spectrum, profile with microstruct…

Comment on "Mode Structure and Orbital Angular Momentum of Spatiotemporal Optical Vortex (STOV) Pulses"
We report a mathematical error and a misinterpretation in arXiv:2103.03263v4 [Phys. Rev. Lett. {\bf 127}, 193901 (2021)] that has led to a debate about the nature of the transverse orbital angular momentum (OAM) of spatiotemporal optical vortices (STOVs). The transverse OAM of STOVs evaluated theoretically in that Letter is actually only the intrinsic contribution, while the operators used to evaluate the intrinsic and extrinsic contributions are not Hermitian operators as they may lead to comp…

The invisible black widow PSR J1720-0534: implications for the electron density towards the North Polar Spur
Radio emission from pulsars can be used to map out their distances through dispersion measure (DM), which quantifies the amount of radio pulse dispersion. However, this method relies on accurately modelling the free electron density in the line of sight. Here, we present a detailed study of the multiwavelength emission from PSR J1720$-$0534, a black widow compact binary millisecond pulsar discovered in 2021, which the latest electron density model of the Galaxy (Yao et al. 2017) places at only …

Chandra Study of the Proper Motion of HST-1 in the Jet of M87
The radio galaxy M87 is well known for its jet, which features a series of bright knots observable from radio to X-ray wavelengths. We analyze the X-ray image and flux variability of the knot HST-1 in the jet. Our analysis includes all 112 available \textit{Chandra} ACIS-S observations from 2000-2021, with a total exposure time of $\sim$887 ks. We use de-convolved images to study the brightness profile of the X-ray jet and measure the relative separation between the core and HST-1. From 2003-20…
