The impact of cosmic rays on the interstellar medium and galactic outflows of Milky Way analogues

Posted by klaurent July 25, 2023Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Adrianne Slyz, Julien Devriendt, Yohan Dubois | Summary: During the last decade, cosmological simulations have managed to reproduce realistic and morphologically diverse galaxies, spanning the Hubble sequence. Central to this success was a phenomenological calibration of the few included feedback processes, whilst […]

The Subtle Effects of Mergers on Star Formation in Nearby Galaxies

Posted by klaurent July 25, 2023Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yang A. Li, Luis C. Ho, Jinyi Shangguan, , | Summary: Interactions and mergers play an important role in regulating the physical properties of galaxies, such as their morphology, gas content, and star formation rate (SFR). Controversy exists as to the degree to which these events, […]

Panchromatic Photometry of Low-redshift, Massive Galaxies Selected from SDSS Stripe 82

Posted by klaurent July 25, 2023Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yang A. Li, Luis C. Ho, Jinyi Shangguan, Ming-Yang Zhuang, Ruancun Li | Summary: The broadband spectral energy distribution of a galaxy encodes valuable information on its stellar mass, star formation rate (SFR), dust content, and possible fractional energy contribution from nonstellar sources. We present a […]

Critical fates induced by interaction competition in the three-dimensional tilted Dirac semimetals

Posted by klaurent July 25, 2023August 8, 2023Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jie-Qiong Li, Wen-Hao Bian, Qiao-Chu Zhang, Xiao-Yue Ren | Summary: The interplay between Coulomb interaction, electron-phonon coupling, and phonon-phonon coupling has a significant impact on the low-energy behavior of three-dimensional type-I tilted Dirac semimetals. To investigate this phenomenon, we construct an effective theory, calculate one-loop […]

Classical radiation fields for scalar, electromagnetic, and gravitational waves with spacetime-symmetry breaking

Posted by klaurent July 25, 2023Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Quentin G. Bailey, Alexander S. Gard, Nils A. Nilsson, Rui Xu, Lijing Shao | Summary: An effective field theory framework is used to investigate some Lorentz-violating effects on the generation of electromagnetic and gravitational waves, complementing previous work on propagation. Specifically we find solutions to a modified, […]

Photochemical origin of SiC$_2$ in the circumstellar envelope of carbon-rich AGB stars revealed by ALMA

Posted by klaurent July 25, 2023August 8, 2023Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yanan Feng, Xiaohu Li, Tom J. Millar, Ryszard Szczerba, Ke Wang | Summary: Whether SiC$_2$ is a parent species, that is formed in the photosphere or as a by-product of high-temperature dust formation, or a daughter species, formed in a chemistry driven by the photodestruction of parent […]

Extra-tensor-induced origin for the PTA signal: No primordial black hole production

Posted by klaurent July 24, 2023Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Mohammad Ali Gorji, Misao Sasaki, Teruaki Suyama, , | Summary: Recently, pulsar timing array (PTA) collaborations announced evidence for an isotropic stochastic gravitational wave (GW) background. The origin of the PTA signal can be astrophysical or cosmological. In the latter case, the so-called secondary scalar-induced GW scenario […]
