Religion Clause: 11th Circuit: Government Can Insist on Secular Presenters in Intervention Program for Domestic Abusers

Charlie Kirk initially made his name by being the most obnoxious of the “debate me” bros.
Republicans love men who are the worst, so it turned him into an overnight MAGA star.
Kirk, who wanted to seem like a young and “hip” Republican when he started out, claimed in 2016 to have a “secular worldview.”
Two years later, he criticized older Republicans for ignoring the “separation of church and state.”
His organization, Turning Point USA, cited their values as “fiscal re…

How Charlie Kirk turned to religion to level up his racism
The "debate me" bro reveres a minister who claimed God cursed Black people to be "servile"

Flight masks of the Roman Space Telescope Coronagraph Instrument
Over the past two decades, thousands of confirmed exoplanets have been detected. The next major challenge is to characterize these other worlds and their stellar systems. Much information on the composition and formation of exoplanets and circumstellar debris disks can only be achieved via direct imaging. Direct imaging is challenging because of the small angular separations (< 1 arcsec) and high star-to-planet flux ratios such as ~1e9 for a Jupiter analog or ~1e10 for an Earth analog in the vi…

Safe Landing on Small Celestial Bodies with Gravitational Uncertainty Using Disturbance Estimation and Control Barrier Functions
Soft landing on small celestial bodies (SCBs) poses unique challenges, as uncertainties in gravitational models and poorly characterized, dynamic environments require a high level of autonomy. Existing control approaches lack formal guarantees for safety constraint satisfaction, necessary to ensure the safe execution of the maneuvers. This paper introduces a control that addresses this limitation by integrating trajectory tracking, disturbance estimation, and safety enforcement. An extended hig…

Confronting infrared divergences in de Sitter: loops, logarithms and the stochastic formalism
A well-established result in quantum field theory in four-dimensional de Sitter space is that the vacuum state of a massless scalar field breaks the de Sitter isometry group, leading to time-dependent (secular) growth in correlation functions computed in inflationary coordinates. This behavior is widely believed to extend to more general theories involving light scalar fields with weak non-derivative interactions. In such cases, secular growth is thought to be further amplified by loop correcti…

Transfer using Fourier transform and minimal representation of $E_7$
In this paper, we study the Sakellaridis-Venkatesh conjecture for the rank-1 spherical variety $X=\text{Spin}_9\backslash F_4$ using an exceptional theta correspondence. We establish the correct transfer map satisfying relative character identities in this case and show that our transfer map agrees with the formula in (Sakellaridis, 2021). Moreover, we show how our techniques lead to a characterization of $X$-relatively cuspidal representations.

Evolving magnetic lives of Sun-like stars. I. Characterisation of the large-scale magnetic field with Zeeman-Doppler imaging
Planets orbiting young, solar-type stars are embedded in a more energetic environment than that of the solar neighbourhood. They experience harsher conditions due to enhanced stellar magnetic activity and wind shaping the secular evolution of a planetary atmosphere. This study is dedicated to the characterisation of the magnetic activity of eleven Sun-like stars, with ages between 0.2 and 6.1 Gyr and rotation periods between 4.6 and 28.7 d. Based on a sub-sample of six stars, we aim to study th…

TrES-1 b: A Case Study in Detecting Secular Evolution of Exoplanet Orbits
We present a comprehensive analysis of transit, eclipse, and radial velocity data of the hot Jupiter TrES-1 b and confirm evidence of orbital variations on secular timescales. Apparent variations due to systemic motion and light travel time effects have been ruled out, indicating that the observed changes are dynamical in origin. Joint modeling of the TrES-1 b data favors an apsidal precession model, but the rapid precession rate of $4^\circ$ yr$^{-1}$ cannot be explained without invoking an un…

Ferroelectric Nematic Liquid Crystal-Based Silicon Photonic Modulator Demonstrated at 102 Gbit/s PAM-4
We present the first demonstration of a hybrid integrated silicon and ferroelectric nematic liquid crystal modulator achieving 102~Gbit per second PAM-4 modulation. Operating within the C-band at a 3.5 V DC bias, this Pockels-based Mach-Zehnder modulator exhibits a $V_πL_\mathrm{AC}$ of 0.3 V$\cdot$cm.
