Connection between Stellar Mass Distributions within Galaxies and Quenching Since z = 2 [PDF]

open access: yes, 2017
We study the history from to of the stellar mass assembly of quiescent and star-forming galaxies in a spatially resolved fashion. For this purpose, we use multi-wavelength imaging data from the Hubble Space Telescope (HST) over the GOODS fields and the ...

Central BH Mass of Tidal Disruption Event Candidate SDSS J0159 through Long-term Optical Variabilities

open access: yesThe Astrophysical Journal, 2023
In this manuscript, central BH mass is determined in the tidal disruption event (TDE) candidate SDSS J0159, through the 9 yr long variabilities, in order to check whether the virial BH mass is consistent with the mass estimated by other independent ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Stellar mass functions: methods, systematics and results for the local Universe [PDF]

open access: yes, 2016
We present a comprehensive method for determining stellar mass functions, and apply it to samples in the local Universe. We combine the classical 1/Vmax approach with STY, a parametric maximum likelihood method and SWML, a non-parametric maximum ...

Ly Halo Properties and Dust in the Circumgalactic Medium of z ∼ 2 Star-forming Galaxies

open access: yesThe Astrophysical Journal
We present Keck Cosmic Web Imager integral-field unit observations around extended Ly α halos of 27 typical star-forming galaxies with redshifts 2.0 < z < 3.2 drawn from the MOSFIRE Deep Evolution Field survey.

Critical Rates of Stellar Mass Loss [PDF]

open access: yesSymposium - International Astronomical Union, 1979
Many of the effects of mass loss on OB stars have now been explored. Mass loss will cause a star to be overluminous for its mass (though less luminous than a star of its original mass) and, for moderate mass-loss rates, the luminosity decreases at the same rate as the mass contained in the convective core decreases causing the main sequence lifetime to

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Can stellar mass be measured by asteroseismology? [PDF]

open access: yesSymposium - International Astronomical Union, 1988
Theoretical calculations show that the detailed pattern of frequencies from stellar oscillations can in principal produce data that can determine stellar masses independent of other input data.
