Integrated photonic ultrawideband real-time spectrum sensing for 6G wireless networks

Posted by klaurent Peking, This Week: Astrophysics

Kavli Affiliate: Feng Yuan | First 5 Authors: Yuansheng Tao, Yuansheng Tao, , , | Summary: The sixth generation (6G) wireless networks require dynamic spectrum management to optimize the utilization of scarce spectral resources and support emerging integrated sensing and communication (ISAC) applications. This necessitates real-time spectrum sensing (RT-SS) capability with ultrawide measurement range, compact […]

The Spin-orbit alignment of two short period eclipsing binary systems

Posted by klaurent MIT, This Week: Astrophysics

Kavli Affiliate: Avi Shporer | First 5 Authors: Tony Wells, Tony Wells, , , | Summary: We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 and TIC 339607421. TIC 339607421 hosts an M-dwarf companion ($M_B = 0.294 pm 0.013 : […]

Search for low-mass electron-recoil dark matter using a single-charge sensitive SuperCDMS-HVeV Detector

Posted by klaurent Stanford, This Week: Astrophysics

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, SuperCDMS Collaboration, , , | Summary: We present constraints on low mass dark matter-electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water […]

The clustering of C IV and Si IV at the end of reionisation: A perspective from the E-XQR-30 survey

Posted by klaurent Cambridge, This Week: Astrophysics

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Louise Welsh, Louise Welsh, , , | Summary: We aim to study the clustering of metal absorption lines and the structures that they arise in as a function of cosmic time. We focus on C IV and Si IV absorption features that are identified along a given […]

On anomalies and fermionic unitary operators

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Masaki Okada, Masaki Okada, , , | Summary: We point out that fermionic unitary operators which anticommute among themselves appear in various situations in quantum field theories with anomalies in the Hamiltonian formalism. To illustrate, we give multiple derivations of the fact that position-dependent $U(1)$ transformations of […]

Initial results of the TRIUMF ultracold advanced neutron source

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: B. Algohi, B. Algohi, , , | Summary: We report the first results on ultracold neutron production from a new spallation-driven superfluid $^4$He (He-II) source at TRIUMF, which is being prepared for a new, precise measurement of the neutron electric dipole moment. A total of $(9.3 pm […]

Updated bounds on ultra-light dark matter from the tiniest galaxies

Posted by klaurent Chicago, This Week: Astrophysics

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Simon May, Simon May, , , | Summary: The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to $m > 3 times 10^-19,mathrmeV$. This constraint, which excludes the "fuzzy" range of ultra-light dark matter from comprising all of the DM, […]

Coupling of a nuclear transition to a Surface Acoustic Wave

Posted by klaurent Stanford, This Week: Astrophysics

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Albert Nazeeri, Albert Nazeeri, , , | Summary: Mechanical modulation of recoilless nuclear transitions allows the dynamic control of gamma-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate such control by coupling a film […]
