Mini-Quenching of High-Redshift Galaxies by Bursty Star Formation

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 […]

TOI-2498 b: A hot bloated super-Neptune within the Neptune desert

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 […]

The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements

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, […]

Constraints on the Hubble constant from Supernova Refsdal’s reappearance

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 […]

A 1.55 R$_{oplus}$ habitable-zone planet hosted by TOI-715, an M4 star near the ecliptic South Pole

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 […]

Anderson self-duality of topological modular forms, its differential-geometric manifestations, and vertex operator algebras

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 […]

Quantifying Uncertainties on the Tip of the Red Giant Branch Method

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 […]

Ultra low-mass and small-radius white dwarfs made of heavy elements

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 $M_odot$ […]
