HD 175167b is a cold ($P_{b}\sim 1200$ days) Jupiter with a minimum mass of
$M_{p}\sin i=7.8\pm3.5\ M_J$ orbiting a Sun-like star, first discovered by the
Magellan Planet Search Program based on MIKE observations. Through a joint
analysis of the MIKE data and the Gaia two-body orbital solution, Winn (2022)
found a comp... | http://arxiv.org/abs/2310.14568v1 |
In this paper, we consider Einstein-Hilbert gravity in the presence of
cosmological constant with cylindrical symmetry to introduce the black hole
solution of this model. Here, we solve the Einstein's vacuum field equation,
and then we calculate the appropriate metric for this problem. | http://arxiv.org/abs/2303.14450v1 |
In this article, we will first-time model galactic black holes in pure
Lovelock gravity. Even though working with higher spacetime dimensions, we
assume (implicitly) the Hernquist-type mass profile for the galaxy in such a
way that the horizon structure of a pure LoveLock black hole remains intact. In
this way, we will... | http://arxiv.org/abs/2309.01760v2 |
The Kubo formula is a cornerstone in our understanding of near-equilibrium
transport phenomena. While conceptually elegant, the application of Kubo's
linear-response theory to interesting problems is hindered by the need for
algorithms that are accurate and scalable to large lattice sizes beyond one
spatial dimension. ... | http://arxiv.org/abs/2307.09690v2 |
The interaction among inverter-based resources (IBRs) and power network may
cause small-signal stability issues, especially in low short-circuit-level
grids. Besides, integrating static synchronous compensators (STATCOMs) in a
multi-IBR system for voltage support can deteriorate small-signal stability.
However, it is s... | http://arxiv.org/abs/2303.04643v5 |
We discuss the aspects of axion-like-particles (ALPs) searches with
Light-Shining-through-Wall (LSW) experimental setups consisted of two
radio-frequency cavities. We compare the efficiencies of three setups which
involve the cavity pump modes and external magnetic fields. Additionally, we
discuss the sensitivity depen... | http://arxiv.org/abs/2303.15996v3 |
Joint probabilistic data association (JPDA) filter methods and multiple
hypothesis tracking (MHT) methods are widely used for multitarget tracking
(MTT). However, they are known to exhibit undesirable behavior in tracking
scenarios with targets in close proximity: JPDA filter methods suffer from the
track coalescence e... | http://arxiv.org/abs/2308.06326v2 |
In this work, we propose trait-based merge trees a generalization of merge
trees to feature level sets, targeting the analysis of tensor field or general
multi-variate data. For this, we employ the notion of traits defined in
attribute space as introduced in the feature level sets framework. The
resulting distance fiel... | http://arxiv.org/abs/2308.09015v1 |
We use Dark Energy Survey Year 3 (DES Y3) clusters with archival X-ray data
from XMM-Newton and Chandra to assess the centering performance of the
redMaPPer cluster finder and to measure key richness observable scaling
relations. In terms of centering, we find that 10-20% of redMaPPer clusters are
miscentered with no s... | http://arxiv.org/abs/2310.13207v1 |
Abundant evidence has tracked the labour market and health assimilation of
immigrants, including static analyses of differences in how foreign-born and
native-born residents consume health care services. However, we know much less
about how migrants' patterns of health care usage evolve with time of
residence, especial... | http://arxiv.org/abs/2304.00482v1 |
Photometric observations and analysis of twelve previously poorly studied
contact binary systems is presented. All show total eclipses and have extremely
low mass ratios ranging from 0.072 to 0.15. Also, all show characteristics of
orbital instability with mass ratios within the theoretical orbital instability
range. A... | http://arxiv.org/abs/2306.15190v1 |
Motivated by the thermodynamics of black hole solutions conformal to
stationary solutions, we study the geometric invariant theory of null
hypersurfaces. It is well-known that a null hypersurface in a Lorentzian
manifold can be treated as a Carrollian geometry. Additional structure can be
added to this geometry by choo... | http://arxiv.org/abs/2310.08141v2 |
We prove that the closure of the numerical range of a $(n+1)$-periodic and
$(2m+1)$-banded Toeplitz operator can be expressed as the closure of the convex
hull of the uncountable union of numerical ranges of certain symbol matrices.
In contrast to the periodic $3$-banded (or tridiagonal) case, we show an
example of a $... | http://arxiv.org/abs/2308.12353v1 |
