Ranked choice voting (RCV)
is an increasingly popular electoral institution that has been posited by reformers and media outlets to produce transformative effects on electoral outcomes and representation.
This article finds no empirical support for the proposition that RCV changed fiscal outcomes or the ideological composition of city councils

Probing the ionizing photon output of galaxies near cosmic dawn with the patchy kSZ effect
A key result from JWST's first cycles is that galaxy formation was well underway by $z=10$. The implications of these early galaxies for reionization are less clear, however. The CMB is one of the few windows into the ionization state of the IGM during reionization's first half, providing an important probe of the ionizing photon sources at those times. Meanwhile, measurements of the Lyman-$α$ forest in the spectra of high-$z$ quasars have improved to the level of tightly constraining the timi…

Obzwar die allermeiste Werbung nicht schafft, mir einen Kaufanreiz zu injizieren, so doch mich zu nerven oder gar anzutriggern. Grad eben wieder „…reinigt neunmal effektiver!“ und in meinem Kopf geht sofort an: als was? Neunmal effektiver als Christian Lindner? Das ist ein Komparativ, verdammt noch mal! Der ist dazu da was zu vergleichen. Du kannst nicht einfach sagen „Drei ist kleiner!“ Also kannst du schon, aber das ist halt semantisch Blödsinn – insofern, paßt zu Werbung: da ist ständig i…

oLIMpus: An Effective Model for Line Intensity Mapping Auto- and Cross- Power Spectra in Cosmic Dawn and Reionization
Line-intensity mapping (LIM) is emerging as a powerful probe of the high-redshift Universe, with a growing number of LIM experiments targeting various spectral lines deep into the epochs of reionization and cosmic dawn. A key remaining challenge is the consistent and efficient modeling of the diverse emission lines and of the observables of different surveys. Here, we present oLIMpus, a fully analytical effective model to study LIM auto- and cross- power spectra. Our work builds on the 21-cm ef…

Context-stratified Mendelian randomization: exploiting regional exposure variation to explore causal effect heterogeneity and non-linearity
Mendelian randomization (MR) uses genetic variants as instrumental variables to make causal claims. Standard MR approaches typically report a single population-averaged estimate, limiting their ability to explore effect heterogeneity or non-linear dose-response relationships. Existing stratification methods, such as residual-based and doubly-ranked stratified MR, attempt to overcome this but rely on strong and unverifiable assumptions. We propose an alternative, context-stratified Mendelian ran…

The AdS Perspective on the Nonlinear Tails in Black Hole Ringdown
Black holes gradually settle into their static configuration by emitting gravitational waves, whose amplitude diminish over time according to a power-law decay at fixed spatial locations. We show that the nonlinear tails in the presence of a quadratic source, which have been recently found to potentially dominate over the linear ones, can be simply derived from the AdS$_2$$\times$S$^2$ spacetime perspective with their amplitudes being related to the Aretakis constants.

In-Context Learning as an Effective Estimator of Functional Correctness of LLM-Generated Code
When applying LLM-based code generation to software development projects that follow a feature-driven or rapid application development approach, it becomes necessary to estimate the functional correctness of the generated code in the absence of test cases. Just as a user selects a relevant document from a ranked list of retrieved ones, a software generation workflow requires a developer to choose (and potentially refine) a generated solution from a ranked list of alternative solutions, ordered …

Patchy Helium and Hydrogen Reionization from the Kinetic Sunyaev-Zel'dovich Effect and Galaxies
Upcoming cosmic microwave background (CMB) experiments will measure temperature fluctuations on small angular scales with unprecedented precision, enabling improved measurements of the kinetic Sunyaev-Zel'dovich (kSZ) effect. This secondary anisotropy has emerged as a valuable probe of the distribution of ionized electrons in the post-recombination Universe. Although the sensitivity of the kSZ effect has recently been utilized to study the high-redshift epoch of hydrogen (H) reionization, its r…
