SPIDER is a balloon-borne instrument designed to map the polarization of the millimeter-wave sky at large angular scales. SPIDER targets the B-mode signature of primordial gravitational waves in the cosmic microwave background (CMB), with a focus on mapping a large sky area with high fidelity at multiple frequencies. SPIDER's first longduration balloon (LDB) flight in January 2015 deployed a total of 2400 antenna-coupled Transition Edge Sensors (TESs) at 90 GHz and 150 GHz. In this work we review the design and in-flight performance of the SPIDER instrument, with a particular focus on the measured performance of the detectors and instrument in a space-like loading and radiation environment. SPIDER's second flight in December 2018 will incorporate payload upgrades and new receivers to map the sky at 285 GHz, providing valuable information for cleaning polarized dust emission from CMB maps.

  1. Spinfoams, $\gamma$-duality and parity violation in primordial gravitational waves

    gr-qc 2024-03 unverdicted novelty 6.0 of 10

    γ-duality in the EPRL spinfoam model determines the relation between parity-even and parity-odd terms in an effective gravity theory, allowing the Barbero-Immirzi parameter to be measured from inflationary tensor observables.

  2. Is the formation of primordial black holes from single-field inflation compatible with standard cosmology?

    astro-ph.CO 2024-12 conditional novelty 5.0 of 10

    Producing primordial black holes in single-field inflation typically forces more than about 55 e-folds after CMB-mode exit, conflicting with standard reheating unless the model is retuned or reheating is exotic.

  3. B-mode Power Spectrum of CMB via Polarized Compton Scattering

    astro-ph.CO 2019-09 conditional novelty 5.0 of 10

    Compton scattering off partially polarized electrons can generate B-mode polarization from scalar density perturbations, with an amplitude proportional to the square of the electron polarization asymmetry.

  4. Reheating in geometric Weyl-invariant Einstein-Cartan gravity

    gr-qc 2026-01 unverdicted novelty 4.0 of 10

    Reheating temperature and equation-of-state parameter assumptions in Weyl-invariant Einstein-Cartan gravity models significantly alter predicted inflationary observables.

  5. Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

    astro-ph.CO 2022-03 accept novelty 2.0 of 10

    The paper reviews cosmological tensions including the H0 and S8 discrepancies and explores new physics models that could explain them.
