The Host Galaxy and Rapidly Evolving Broad-line Region in the Changing-look Active Galactic Nucleus 1ES 1927+654

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Ruancun Li, Luis C. Ho, Claudio Ricci, Benny Trakhtenbrot, Iair Arcavi | Summary: Changing-look active galactic nuclei (AGNs) present an important laboratory to understand the origin and physical properties of the broad-line region (BLR). We investigate follow-up optical spectroscopy spanning $sim 500$ days after the outburst of […]

Monojet signatures from gluino and squark decays

Posted by klaurent Tokyo

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Iñaki Lara, Trygve Buanes, Rafał Masełek, Mihoko M. Nojiri, Krzysztof Rolbiecki | Summary: In this paper, we study the monojet and dijet channels at the LHC as a tool for searching for squarks and gluinos. We consider two separate scenarios. In the first scenario we postulate […]

The Star-forming Main Sequence of the Host Galaxies of Low-redshift Quasars

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ming-Yang Zhuang, Luis C. Ho, , , | Summary: We investigate the star-forming main sequence of the host galaxies of a large, well-defined sample of 453 redshift $sim$0.3 quasars with previously available star formation rates by deriving stellar masses from modeling their broad-band ($grizy$) spectral energy […]

Towards precision particle background estimation for future X-ray missions: correlated variability between Chandra ACIS and AMS

Posted by dbos MIT

Kavli Affiliate: Richard Foster | First 5 Authors: Catherine E. Grant, Eric D. Miller, Marshall W. Bautz, Richard Foster, Ralph P. Kraft | Summary: A science goal of many future X-ray observatories is mapping the cosmic web through deep exposures of faint diffuse sources. Such observations require low background and the best possible knowledge of […]

2022 Upgrade and Improved Low Frequency Camera Sensitivity for CMB Observation at the South Pole

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: A. Soliman, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: Constraining the Galactic foregrounds with multi-frequency Cosmic Microwave Background (CMB) observations is an essential step towards ultimately reaching the sensitivity to measure primordial gravitational waves (PGWs), the sign of inflation after the Big-Bang […]
