Abstract

Supernovae (SNe) are excellent probes of the physical, chemical, and cosmological context of galaxies across the history of the Universe. The James Webb Space Telescope (JWST ) has a truly unique combination of wavelength, sensitivity, and resolution, providing a new window into SN physics, progenitors, dust production, redshift evolving stellar populations, and cosmology since its launch. Here we summarize the astounding observations JWST has made of SNe in its first few years of operations, as well as the corresponding advancements in our understanding of the Universe. This includes detailed views of nearby SNe, the first spectroscopic samples of high-z SNe, and a significant number of gravitationally lensed SNe valuable for both cosmological inference and high signal-to-noise (S/N) spectroscopy. While the upcoming Nancy Grace Roman Space Telescope is expected to revolutionize space-based time-domain astronomy, JWST and its unique capabilities will continue to play a complementary role by providing high-precision spectroscopic and photometric data for a broad range of SN science cases.

The many boundaries of the stratified dark matter halo

We review the physics of halo collapse giving rise to various halo boundaries, as well as their identification, observation, and applications. The classical halo is typically defined as a monolithic, virialized object enclosed within its virial radius -- a definition which, however, does not account for ongoing halo growth. Continuous accretion causes the orbits of infalling particles to shrink over time, confining newly accreted material in a growing layer outside the virialized region. Several novel halo boundaries, such as the splashback and depletion radii, have recently been proposed to characterize this growth layer from different perspectives. Along with the turnaround radius, which operates on an even larger scale to enclose the entire infall region, these multiple boundaries comprise an extended view of a dark matter halo as a stratified structure. Theoretical models can largely explain the existence of various boundaries, while challenges remain in providing unified and quantitative predictions of their properties. The multiple boundaries open new avenues for observing halo growth and may substantially improve our understanding and modeling of cosmic structure formation. We provide a python package, SpheriC, implementing the key spherical collapse models.

Selection--Clustering Coupling and Pair-Midpoint Anisotropy from Observer Motion

Observer motion couples source selection, clustering, and estimator normalization in cosmological pair statistics. Existing calculations distinguish the source-count dipole from the modulation of clustering, including selection-dependent bias. We develop an observable-level formulation that retains arbitrary marked pair kernels, nonfactorizable pair inclusion, and explicit reference measures. Its independent-selection limit expresses the residual as a covariance of the selection score with pair excess; in a rank-one bias model this is the logarithmic response of the selected mean bias and recovers the corresponding bias-derivative description. Two populations can have the same count-dipole coefficient and isotropic correlation but opposite two-point boost responses. We show that local division by endpoint means is not equivalent to a scalar normalization of integrated pair counts, and derive the contact terms and self-pair subtraction required for discrete harmonic estimators. Exchange symmetry permits pair-midpoint anisotropy but forbids an ordinary unordered same-tracer separation dipole. The known neighboring-multipole templates are recovered, with explicit conditions for velocity--selection degeneracy and its uncertainty cost. Finite-boost forward models independently test the response, including a nonfactorizable retained-pair example. The result is a common framework for bias-response limits, general pair selection, normalization, and covariance conventions; the numerical illustrations are controlled models rather than survey forecasts. An observational route is specified through radio and infrared catalog selections, full-pipeline response calibration, and common-velocity consistency tests.

Primordial Black Hole interpretation of the subsolar merger event S251112cm

The LIGO-Virgo-KAGRA (LVK) candidate event S251112cm suggests that at least one component has a subsolar mass. Since such objects cannot be produced through standard stellar evolution, this observation provides a possible indication of nonstandard formation channels. Primordial black holes (PBHs), formed from the collapse of primordial density fluctuations in the early Universe, are a well-motivated candidate. We investigate the interpretation of S251112cm as the merger of two PBHs in the mass range $0.20$-$1\,M_\odot$, within the parameter space directly covered by the O4a subsolar search. Combining analytic estimates of the PBH merger rate with current observational constraints on their abundance and the sensitivity of LVK searches, we compute the probability of observing such an event. We consider both a monochromatic PBH mass function and extended lognormal distributions. Within the relaxed constraint scenario, the detection probability can approach unity toward the upper end of the mass range. A lognormal mass distribution of moderate width can enhance the probability relative to the monochromatic case, whereas a broader distribution can instead suppress it. Our results show that a PBH interpretation of S251112cm is compatible with current observational bounds even for a subdominant PBH abundance. Owing to the dependence of our results on astrophysical uncertainties, such as those affecting the constraints on the abundance of PBHs, they cannot be regarded as conclusive with respect to the nature of the detected event. At the same time, our analysis highlights the potential of subsolar gravitational wave events as a probe of PBHs and their contribution to dark matter.
