A Study of Afterglow Signatures in NaI and CsI Scintillator Modules for the Background and Transient Observer Instrument on COSI

Posted by klaurent Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hannah Gulick, Hiroki Yoneda, Tadayuki Takahashi, Claire Chen, Kazuhiro Nakazawa | Summary: We present measurements of the afterglow signatures in NaI(Tl) and CsI(Tl) detector modules as part of the Background and Transient Observer (BTO) mission detector trade-study. BTO is a NASA Student Collaboration Project flying on the […]

The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Complete Size Distributions for the 100 Brightest Disks Across Multiplicity and SED Classes

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova, Trisha Bhowmik, Ms. Prachi Chavan | Summary: The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d $sim$ 140-200 pc). We present the complete continuum size distribution […]

Time-resolved spectral diffusion of a multimode mechanical memory

Posted by klaurent Delft

Kavli Affiliate: Simon Groblacher | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: High-frequency phonons hold great promise as carriers of quantum information on-chip and as quantum memories. Due to their coherent interaction with several systems, their compact mode volume, and slow group velocity, multiple experiments have recently demonstrated coherent transport of information […]

Cold Gas and Star Formation in the Phoenix Cluster with JWST

Posted by klaurent MIT

Kavli Affiliate: Michael McDonald | First 5 Authors: Michael Reefe, Michael Reefe, , , | Summary: We present integral field unit observations of the Phoenix Cluster with the JWST Mid-infrared Instrument’s Medium Resolution Spectrometer (MIRI/MRS). We focus this study on the molecular gas, dust, and star formation in the brightest cluster galaxy (BCG). We use […]

A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Posted by klaurent MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Marc Hon, Saul Rappaport, Avi Shporer, Andrew Vanderburg, Karen A. Collins | Summary: We report the discovery of BD+05$,$4868$,$Ab, a transiting exoplanet orbiting a bright ($V=10.16$) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) reveal variable transit […]

Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source

Posted by klaurent MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Muryel Guolo, Sean Lockwood, Andrew Mummery, Dheeraj R. Pasham | Summary: X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray […]

Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole

Posted by klaurent MIT

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Megan Masterson, , , | Summary: Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the newly-discovered quasi-periodic eruptions (QPEs), are garnering further interest in […]

Anisotropic moiré band flattening in twisted bilayers of M-valley MXenes

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Kejie Bao, Kejie Bao, , , | Summary: Experimental studies on moir’e materials have predominantly focused on twisted hexagonal lattice with low-energy states near the $Gamma$- or K-points, where the electronic dispersion is typically isotropic. In contrast, we introduce a class of semiconducting transition metal carbides (MXenes) […]
