Are there observational measurements of the star formation rate in brightest cluster galaxies ?
Best insight from top research papers
Observational measurements of the star formation rate (SFR) in brightest cluster galaxies (BCGs) have been conducted. The CLASH X-ray selected sample of 20 galaxy clusters includes BCGs with significant SFRs, as inferred from photometric estimates of UV and Hα+[\ion{N}{2}] emission . These measurements are supplemented with fluxes measured from spectra obtained with the SOAR telescope . Mid-IR spectra also show indications of star formation in BCGs . The incidence of emission-line BCGs in X-ray selected clusters is higher than in optically-selected clusters . Additionally, a study on the relation between SFR and the luminosity of the brightest star cluster in a galaxy provides further evidence of star formation in BCGs .

How do astronomers study and observe star formation processes within nebulae?4 answersAstronomers study and observe star formation processes within nebulae using various techniques. They analyze the kinematics of young stellar populations in nebulae to understand their formation processes. They also use near-infrared observations to detect outflows and trace them back to their driving sources. Additionally, astronomers evaluate the relative importance of gravity, turbulence, magnetic fields, geometry, and radiative feedback in governing the density structure and star formation activity within nebulae. They also conduct systematic studies of objects transitioning from post-AGB to planetary nebulae to gain insights into the mechanisms leading to the observed morphologies. Furthermore, astronomers critically examine the atomic physics relevant to gaseous nebulae, including the population structure of bound electrons, using modelling software. These approaches help astronomers gain a comprehensive understanding of the star formation processes occurring within nebulae.
What is the relationship between AGN obscuration and star formation rate?4 answersThe relationship between AGN obscuration and star formation rate is complex and varies depending on the specific conditions. Some studies suggest that AGN can enhance the star formation rate of their host galaxies, particularly when the galaxies lie below the main sequence of star formation. However, other studies indicate that AGN can also quench the star formation of their host galaxies, especially when the galaxies lie above the main sequence. Additionally, the presence of AGN can affect the average dust temperatures of galaxies, potentially influencing the shape of the well-known L_IR-T_dust relation. Overall, the impact of AGN obscuration on star formation rate is influenced by factors such as redshift, X-ray luminosity, and the location of the galaxy relative to the main sequence.
