  Pillars of Creation

  The Pillars of Creation are clouds of gas and dust stretching several light-years within the Eagle Nebula. Their shapes are created by strong stellar winds and high-energy radiation from hot, newly formed stars in star cluster NGC 6611, which lies at the center of the nebula. These high-energy emissions heat the dust molecules on the […] The post Pillars of Creation appeared first on NASA Science.

  Cassiopeia A Supernova (B) (2023)

  Using NASA’s James Webb Space Telescope, astronomers uncovered a mysterious feature within the remnant, nicknamed the “Green Monster,” alongside a puzzling network of ejecta filaments forming a web of oxygen-rich material. When combined with X-rays from Chandra, the data helped astronomers shed light on the origin of the Green Monster and revealed new insights into […] The post Cassiopeia A Supernova (B) (2023) appeared first on NASA Science.

  Higgs-like inflation under ACTivated mass

  Recent analyses that combine the latest data from the Atacama Cosmology Telescope (ACT) with cosmic microwave background observations by BICEP/Keck and Planck, together with the DESI baryon acoustic-baryonic-oscillation (BAO) measurements, have tightened the limits on inflationary scenarios. The joint data set yields a spectral index of primordial scalar perturbations $n_s = 0.9743 \pm 0.0034$ and an upper bound on the tensor-to-scalar ratio of $r < 0.038$. This slight upward shift in $n_s$ puts the previously favored Starobinsky model, and the conventional metric Higgs(-like) inflation--based on a quartic potential with a large non-minimal coupling in the Jordan frame--under tension with observations. In metric Higgs-like inflation the attractor behavior makes the predictions remarkably stable against higher-order operators, so modifying $n_s$ through such terms is difficult. In this paper, I show that adding a quadratic mass term to the Jordan-frame potential can raise $n_s$ and restore compatibility with the new data. I also discuss how this mass term can naturally arise from threshold effects in Higgs inflation.
