Kinematical fingerprints of star cluster early dynamical evolution [PDF]

open access: yes, 2014
We study the effects of the external tidal field on the violent relaxation phase of star clusters dynamical evolution, with particular attention to the kinematical properties of the equilibrium configurations emerging at the end of this phase.We show ...

Insights into pegRNA design from editing of the cardiomyopathy‐associated phospholamban R14del mutation

open access: yesFEBS Letters, EarlyView.
This study reveals how prime editing guide RNA (pegRNA) secondary structure and reverse transcriptase template length affect prime editing efficiency in correcting the phospholamban R14del cardiomyopathy‐associated mutation. Insights support the design of structurally optimized enhanced pegRNAs for precise gene therapy.

Be stars in young clusters

open access: yesThe Astrophysical Journal, 1994
Photometric Ha and HP line indices for 71 B stars in seven galactic clusters are presented. Some stars in three of the clusters were observed at two epochs. Using these data nine Be stars were identified. Three of them were previously detected as emission-line stars, while six do not appear to have been previously recognized as such.

Deep Galaxy Stellar Mass Functions As a Function of Star Formation Rate in the Virgo Cluster Environment

open access: yesThe Astrophysical Journal
We analyze deep ( M _* ≳ 10 ^7 M _⊙ ) galaxy stellar mass functions (SMFs) of the Virgo cluster using stellar masses derived as part of the Next Generation Virgo Survey. The total SMF has a slope of $\alpha =-1.3{5}_{-0.02}^{+0.02}$ , which is similar to

Star Cluster Formation and Feedback [PDF]

open access: yes, 2014
Stars do not generally form in isolation. Instead, they form in clusters, and in these clustered environments newborn stars can have profound effects on one another and on their parent gas clouds.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Probing Obscured Star Formation in Galaxy Clusters Using JWST Medium-band Images: 3.3 μm PAH Emitter Sample in A2744

open access: yesThe Astrophysical Journal Supplement Series
Star-forming galaxies in galaxy clusters play a crucial role in understanding the advanced stages of galaxy evolution within dense environments. We present a sample of 3.3 μ m polycyclic aromatic hydrocarbon (PAH)-bright galaxies in the A2744 galaxy ...

Universal Upper End of the Stellar Initial Mass Function in the Young and Compact LEGUS Clusters

open access: yesThe Astrophysical Journal, 2023
We investigate the variation in the upper end of the stellar initial mass function (uIMF) in 375 young and compact star clusters in five nearby galaxies within ∼5 Mpc. All the young stellar clusters (YSCs) in the sample have ages ≲ 4 Myr and masses above

Quenching of the star formation activity in cluster galaxies [PDF]

open access: yes, 2016
We study the star formation quenching mechanism in cluster galaxies by fitting the spectral energy distribution (SED) of the Herschel Reference Survey, a complete volume-limited K-band-selected sample of nearby galaxies including objects in different ...
