Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Christa DeCoursey, Eiichi Egami, Fengwu Sun, Arshia Akhtarkavan, Rachana Bhatawdekar | Summary: The James Webb Space Telescope (JWST) discovered 79 transients out to $z$$sim$4.8 through the JADES Transient Survey (JTS), but the JTS did not find any $z$$>$5 transients. Here, we present the first photometric evidence of […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Ronny Frumkin, Yonit Hochberg, Eric Kuflik, Hitoshi Murayama, | Summary: Inverse decays are an interesting avenue for producing dark matter in the early universe. We study in detail various phases of dark matter parameter space where inverse decays control its abundance, expanding on our work of INDY […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald, Kevin B. Stevenson, Sydney Jenkins | Summary: We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with JWST’s Mid-Infrared Instrument […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Clarence Chang, T. J. Hobbs, Dafei Jin, Yi Li, Marharyta Lisovenko | Summary: We introduce an array-scalable, magnon-based detector (MOSAIC) to search for the spin-dependent interactions of electron-coupled axion dark matter. These axions can excite single magnons in magnetic targets, such as the yttrium iron garnet (YIG) […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Saikat Das, Soebur Razzaque, Nestor Mirabal, Nicola Omodei, Kohta Murase | Summary: We search for possible GeV-TeV gamma-ray imprints of ultrahigh-energy (UHE; $gtrsim 0.1$ EeV) cosmic ray (CR) acceleration in the large-scale structures surrounding the brightest gamma-ray burst (GRB) explosion, GRB 221009A. Using 1.25 years of post-event […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, Y. Ahn | Summary: We measure the time-integrated $CP$ asymmetry in $D^0 to K^0_{rm S} K^0_{rm S}$ decays reconstructed in $e^+e^-to c{overline c}$ events collected by the Belle and Belle II experiments. The corresponding data samples have integrated luminosities of […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We present the results of a search for charged-lepton-flavor violating decays $tau^{-} rightarrow ell^{-}K_{S}^{0}$, where $ell^{-}$ is either an electron or a muon. We combine $e^+e^-$ data samples recorded by the Belle II experiment at the […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Makoto A. Johnstone, George C. Privon, Loreto Barcos-Munoz, A. S. Evans, S. Aalto | Summary: Compact Obscured Nuclei (CONs) are heavily obscured infrared cores that have been found in local (ultra)luminous infrared galaxies (U/LIRGs). They show bright emission from vibrationally excited rotational transitions of HCN, known as […]
