Witnessing the star-formation quenching in \(L_{}\) ellipticals

We study the evolution of \(L_{*}\) elliptical galaxies in the color-magnitude diagram in terms of their star-formation history and environment, in an attempt to learn about their quenching process. We have visually extracted 1109 \(L_{*}\) galaxies from a sample of 36500 galaxies that were spectros...

description We study the evolution of \(L_{*}\) elliptical galaxies in the color-magnitude diagram in terms of their star-formation history and environment, in an attempt to learn about their quenching process. We have visually extracted 1109 \(L_{*}\) galaxies from a sample of 36500 galaxies that were spectroscopically selected from Stripe82 of the Sloan Digital Sky Survey. From this sample we have selected 51 ellipticals based on their surface-brightness profile being well-fitted by a single S\(\acute{e}\)rsic profile with S\(\acute{e}\)rsic indices \(3

From this sample we have selected 51 ellipticals based on their surface-brightness profile being well-fitted by a single S\(\acute{e}\)rsic profile with S\(\acute{e}\)rsic indices \(3&lt;n&lt;6\). Our sample consists of 12 blue-cloud \(L_{*}\) ellipticals (BLE), 11 green-valley \(L_{*}\) ellipticals (GLE), and 28 red-sequence \(L_{*}\) ellipticals (RLE). We find that most of the RLEs and GLEs have been quenched only recently, or are still forming stars, based on their [{O\sc{iii}}] and H\(\alpha\) emission, while the BLEs are forming stars vigorously. The star-formation in BLEs is found to be extended over the galaxy and not confined to their central region. In about 40\% of the \(L_{*}\) ellipticals (ten BLEs, four GLEs and five RLEs), star-formation quenching seems to have started only recently, based on the lower [{O\sc{iii}}] emission compared to the [{O\sc{ii}}] and H\(\alpha\) emission, at a given metallicity. We also find that the galaxy color is correlated with the cosmic-web environment, with the BLEs tending to reside in lower-density regions, the RLEs preferring denser, clustered regions, and the GLEs found in either. One possible scenario is that as the star-forming ellipticals migrate into the clusters, their star formation is suffocated by the hot intra-cluster medium.</description><identifier>EISSN: 2331-8422</identifier><identifier>DOI: 10.48550/arxiv.2211.08884</identifier><language>eng</language><publisher>Ithaca: Cornell University Library, arXiv.org</publisher><subject>Color ; Color-magnitude diagram ; Elliptical galaxies ; Metallicity ; Quenching ; Sky surveys (astronomy) ; Star &amp; galaxy formation ; Star formation ; Stars &amp; galaxies</subject><ispartof>arXiv.org, 2022-11</ispartof><rights>2022.
