Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Sandro Tacchella, Anastasia Fialkov, Avishai Dekel, Omri Ginzburg | Summary: The recent observation of a low-mass $z=5.2$ and an intermediate-mass $z=7.3$ (JADES-GS-z7-01-QU) quenched galaxy with JWST / NIRSpec is the first evidence of halted star formation above $zsim 5$. Here we show how bursty star […]
Kavli Affiliate: Sara Seager | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We present the discovery and confirmation of a transiting hot, bloated Super-Neptune using photometry from TESS and LCOGT and radial velocity measurements from HARPS. The host star TOI-2498 is a V = 11.2, G-type (T$_{eff}$ = 5905 $pm$ 12K) solar-like […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Yichao Li, Yougang Wang, Furen Deng, Wenxiu Yang, Wenkai Hu | Summary: This work presents the initial results of the drift-scan observation for the neutral hydrogen (HI) intensity mapping survey with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The data analyzed in this work were collected in […]
Kavli Affiliate: Kaisey Mandel | First 5 Authors: Patrick L. Kelly, Steven Rodney, Tommaso Treu, Simon Birrer, Vivien Bonvin | Summary: In late 2014, four images of Supernova (SN) “Refsdal,” the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images’ discovery, […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Dan Hooper, Gordan Krnjaic, Deheng Song | Summary: We propose that the dark matter of our universe could be sterile neutrinos which reside within the twin sector of a mirror twin Higgs model. In our scenario, these particles are produced through a version of the […]
Kavli Affiliate: Kaisey Mandel | First 5 Authors: Patrick L. Kelly, Steven Rodney, Tommaso Treu, Masamune Oguri, Wenlei Chen | Summary: The gravitationally lensed Supernova Refsdal appeared in multiple images, produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeared in 2014, lens models of the galaxy cluster predicted an additional […]
Kavli Affiliate: Sara Seager | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: A new generation of observatories is enabling detailed study of exoplanetary atmospheres and the diversity of alien climates, allowing us to seek evidence for extraterrestrial biological and geological processes. Now is therefore the time to identify the most unique planets […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita | Summary: Inspired by consideration in heterotic string theory, we construct a morphism of spectra from $mathrm{KO}((q))/mathrm{TMF}$ to $Sigma^{-20}I_{mathbb{Z}} mathrm{TMF}$, which we show to be an isomorphism and to implement the Anderson self-duality of $mathrm{TMF}$. We will use this to factor a related […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman Kayla A. Owens, In Sung Jang | Summary: We present an extensive grid of numerical simulations quantifying the uncertainties in measurements of the Tip of the Red Giant Branch (TRGB). These simulations incorporate a luminosity function composed of 2 magnitudes […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Cheng-Jun Xia, Yong-Feng Huang, Hong-Bo Li, Lijing Shao, Ren-Xin Xu | Summary: Seven ultra low-mass and small-radius white dwarfs (LSPM J0815+1633, LP 240-30, BD+20 5125B, LP 462-12, WD J1257+5428, 2MASS J13453297+4200437, and SDSS J085557.46+053524.5) have been recently identified with masses ranging from $sim$0.02 $M_odot$ to $sim$0.08 $M_odot$ […]
