Towards a comprehensive view of accretion, inner disks, and extinction in classical T Tauri stars: an ODYSSEUS study of the Orion OB1b association

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Caeley V. Pittman, Catherine C. Espaillat, Connor E. Robinson, Thanawuth Thanathibodee, Nuria Calvet | Summary: The coevolution of T Tauri stars and their surrounding protoplanetary disks dictates the timescales of planet formation. In this paper, we present magnetospheric accretion and inner disk wall model fits to […]

The discovery of the 528.6 Hz accreting millisecond X-ray pulsar MAXI J1816-195

Posted by klaurent MIT

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Peter Bult, Diego Altamirano, Zaven Arzoumanian, Deepto Chakrabarty, Jérôme Chenevez | Summary: We present the discovery of 528.6 Hz pulsations in the new X-ray transient MAXI J1816-195. Using NICER, we observed the first recorded transient outburst from the neutron star low-mass X-ray binary MAXI J1816-195 over a […]

Probing early structure and model-independent neutrino mass with high-redshift CMB lensing mass maps

Posted by klaurent Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Frank J. Qu, Blake D. Sherwin, Omar Darwish, Toshiya Namikawa, Mathew S. Madhavacheril | Summary: CMB lensing maps probe the mass distribution in projection out to high redshifts, but significant sensitivity to low-redshift structure remains. In this paper we discuss a method to remove the low-redshift contributions […]

Ultra-bright Coherent Undulator Radiation Driven by Dielectric Laser Accelerator

Posted by dbos Stanford

Kavli Affiliate: Robert L. Byer | First 5 Authors: Yen-Chieh Huang, Robert L. Byer, , , | Summary: A dielectric laser accelerator, operating at optical frequencies and GHz pulse rate, is expected to produce attosec electron bunches with a moderate beam current at high energy. For relativistic electrons, the attosec bunch has a spatial length […]

On the Cosmic Web Elongation in Fuzzy Dark Matter Cosmologies

Posted by klaurent Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Anastasia Fialkov, Philip Mocz, Björn Malte Schäfer, Michael Boylan-Kolchin | Summary: The fuzzy dark matter (FDM) scenario has received increased attention in recent years due to the small-scale challenges of the vanilla Lambda cold dark matter ($Lambda$CDM) cosmological model and the lack of robust experimental […]

Testbed preparation of a small prototype polarization modulator for LiteBIRD low-frequency telescope

Posted by dbos Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Thuong D. Hoang, Tomotake Matsumura, Ryota Takaku, Takashi Hasebe, Tommaso Ghigna | Summary: LiteBIRD is the Cosmic Microwave Background (CMB) radiation polarization satellite mission led by ISAS/JAXA. The main scientific goal is to search for primordial gravitational wave signals generated from the inflation epoch of the Universe. […]

Interpretable Uncertainty Quantification in AI for HEP

Posted by klaurent Chicago

Kavli Affiliate: Brian Nord | First 5 Authors: Thomas Y. Chen, Biprateep Dey, Aishik Ghosh, Michael Kagan, Brian Nord | Summary: Estimating uncertainty is at the core of performing scientific measurements in HEP: a measurement is not useful without an estimate of its uncertainty. The goal of uncertainty quantification (UQ) is inextricably linked to the […]
