Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: This paper presents an alternative way of analysing Baryon Acoustic Oscillation (BAO) distance measurements via rotations to define new quantities Dperp and Dpar. These quantities allow simple tests of consistency with the Planck LCDM cosmology. The parameter Dperp is determined […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Calvin Preston, Keir K. Rogers, Alexandra Amon, George Efstathiou, | Summary: We investigate the degeneracy between the effects of ultra-light axion dark matter and baryonic feedback in suppressing the matter power spectrum. We forecast that galaxy shear data from the Rubin Observatory’s Legacy Survey of Space and […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Dominika Ďurovčíková, Anna-Christina Eilers, Robert A. Simcoe, Louise Welsh, Romain A. Meyer | Summary: We report the discovery of a Lyman $alpha$ emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at $z_{rm QSO}=6.0685$ at a projected distance $sim29 {rm pkpc}$ that is […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Tom Rose, B. R. McNamara, Julian Meunier, A. C. Fabian, Helen Russell | Summary: We present XRISM Resolve observations centered on Hydra-A, a redshift z = 0.054 brightest cluster galaxy which hosts one of the largest and most powerful FR-I radio sources in the nearby Universe. We […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuki Kojima, Yuji Tachikawa, , , | Summary: Let $N(Gamma,G)$ be the number of homomorphisms from $Gamma$ to $G$ up to conjugation by $G$. Physics of four-dimensional $mathcal{N}=4$ supersymmetric gauge theories predicts that $N(Gamma,G)=N(Gamma , tilde G)$ when $Gamma$ is a finite subgroup of $SU(2)$, $G$ is […]
Kavli Affiliate: Sara Seager | First 5 Authors: Katharine Hesse, Ismael Mireles, François Bouchy, Diana Dragomir, Solène Ulmer-Moll | Summary: We report the discovery and confirmation of two planets orbiting the metal-poor Sun-like star, HD 35843 (TOI 4189). HD 35843 c is a temperate sub-Neptune transiting planet with an orbital period of 46.96 days that […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Guglielmo Coloretti, Wanqiang Liu, Mira Littmann, Ian Low | Summary: We consider 2-to-2 scatterings of Higgs bosons in a CP-conserving two-Higgs-doublet model (2HDM) and study the implication of maximizing the entanglement in the flavor space, where the two doublets $Phi_a$, $a=1,2$, can be viewed as […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Unnati Kashyap, Thomas J. Maccarone, Mason Ng, Eliot C. Pattie, Swati Ravi | Summary: We report the first X-ray polarimetric results of the neutron star (NS) low-mass X-ray binary (LMXB) Z-source GX 349+2 using the Imaging X-ray Polarimetry Explorer (IXPE). We discovered that the X-ray source […]
