RNDR noise modeling in first-generation Single electron Sensitive Readout (SiSeRO) devices

Posted by klaurent July 21, 2026July 27, 2026MIT, This Week: Astrophysics

Kavli Affiliate: Marshall Bautz | Summary:Flagship observatories require single-photon detectors with ultra-fast readout, sub-electron noise performance, and scalable large-format architectures. The X-ray Astronomy and Observational Cosmology group at Stanford, in collaboration with the MIT Kavli Institute and MIT Lincoln Laboratory, is developing readout technologies for next-generation detectors. Prototypes employing Single-electron Sensitive Readout (SiSeRO) amplifiers demonstrate […]

Extreme Variability Reveals How the Eddington Ratio Regulates Coronal Power in Active Galactic Nuclei

Posted by klaurent July 21, 2026July 27, 2026Peking, This Week: Astrophysics

Kavli Affiliate: Luis Ho | Summary:The bolometric luminosity ($L_rm bol$) of active galactic nuclei (AGNs) is a key tracer of accretion physics, but its direct determination is often hindered by limited spectral coverage and contamination of the host galaxy. Bolometric corrections ($κ_λ = L_rm bol/L_λ$) offer a practical means of estimating $L_rm bol$, with the […]

The GOLIATH Survey: OVI Absorption Reveals CGM Evolution through the Starburst-to-Quiescent Transition in Massive Galaxies

Posted by klaurent July 21, 2026July 27, 2026MIT, This Week: Astrophysics

Kavli Affiliate: Robert Simcoe | Summary:We present the GOLIATH survey (Galaxies, Outflows, and the Lifecycle of Immense, Active, Transforming Halos), a study of the multiphase circumgalactic medium (CGM) of massive ($langlelog M_star/M_odotrangle approx 11$), blue ($u-r < 1.65$) starburst and post-starburst galaxies at $langle zrangle approx$ 0.43. This work characterizes the warm-hot CGM through OVI […]

Programmable Spin Conversion in Gradient Quantum Matter

Posted by klaurent July 21, 2026July 27, 2026This Week: Theoretical Physics, UCAS

Kavli Affiliate: Mamoru Matsuo | Summary:We propose programmable spin conversion in ultracold gases as gradient quantum matter, whose spin-dependent self-energy varies in space. Quantum kinetic theory shows that a dissipative self-energy curvature turns a force-driven scalar anisotropy into a spin source with mixed longitudinal-transverse momentum parity. Spin-resolved time-of-flight imaging can reveal a transverse spin texture […]

An (in)complete NIRSpec census of Balmer absorption in Type 1 AGN — radiation-driven outflows in little red dots, quasars and variable stars

Posted by klaurent July 21, 2026July 27, 2026Cambridge, This Week: Astrophysics

Kavli Affiliate: Roberto Maiolino | Summary:A notable achievement of the first generation of JWST surveys was the discovery of an abundance of faint high-redshift ($z > 4$) broad-line active galactic nuclei (AGN) in the $L_rm bol < 10^45$~erg~s$^-1$ regime, previously only accessible at $z < 1$. The high prevalence of absorption features in their broad […]

Wave2Body: Rethinking mmWave Human Pose Estimation as Radar-to-Body Token Translation

Posted by klaurent July 21, 2026July 27, 2026Caltech, This Week: Nanoscience

Kavli Affiliate: Wei Gao| Summary:Millimeter-wave (mmWave) radar enables privacy-friendly human sensing, but its sparse point clouds are physical measurements of view-dependent electromagnetic reflections and only indirectly characterize body articulation. Recovering a complete 3D pose from such partial, geometry-dependent observations is therefore under-constrained. Existing methods directly regress joint coordinates from paired radar-pose data, relying on the […]

Data-driven Design of Metal-Organic Frameworks with Tunable Negative Thermal Expansion

Posted by klaurent July 21, 2026July 27, 2026Berkeley, This Week: Nanoscience

Kavli Affiliate: Kristin Persson | Summary:Materials with negative thermal expansion (NTE) are essential for applications requiring precise control of thermal expansion. Owing to their exceptional chemical tunability, flexible architectures, and low-energy lattice vibrations, metal-organic frameworks (MOFs) represent a rich platform for exploring NTE. However, uncovering the structural motifs that govern NTE across the enormous MOF […]

First results for second generation SiSeRO CCD devices

Posted by klaurent July 20, 2026July 27, 2026MIT, This Week: Astrophysics

Kavli Affiliate: Marshall Bautz | Summary:The Astro2020 Decadal recommended the development of a suite of next generation astronomical observatories spanning the X-ray to near-IR spectrum. These programs require fast, extremely low noise detectors to fulfill their science goals. To address this technology gap, Stanford X-ray Astronomy and Observational Cosmology (XOC) group, MIT Lincoln Laboratory (MIT-LL), […]

Coherent Magnons Driven by Photomodulated Anisotropy in Altermagnetic MnTe

Posted by klaurent July 20, 2026July 27, 2026Berkeley, This Week: Nanoscience

Kavli Affiliate: James Analytis| Summary:Manganese telluride ($textMnTe$) has recently emerged as a prototypical $g$-wave altermagnet, providing an ideal platform to investigate the non-equilibrium excitations of altermagnetic order. Here, we report simultaneous spatial mapping of the local equilibrium orientation of the Néel vector, $varphi_L(mathbfr)$, alongside the amplitude, $Δvarphi(mathbfr,t)$, and frequency, $Ω(mathbfr)$, of photoexcited spin waves. Based […]
