Here we present the results of our study of 4 Virgo dwarf ellipticals obtained with the SAURON integral field unit on the William Herschel Telescope (La Palma, Spain). While traditional long-slit observations are likely to miss more complicated kinematic features, with SAURON we are able to study both kinematics and stellar populations in two dimensions, obtaining a much more detailed view of the mass distribution and star formation histo","authors_text":"Agnieszka Ry\\'s, Jes\\'us Falc\\'on-Barroso","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2010-12-01T13:14:01Z","title":"A SAURON study of dwarf elliptical galaxies in the Virgo Cluster: kinematics and stellar populations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1012.0185","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:b5957414c8597f7fe993eee3d1f2bc2eca92103e1d65b2f842f6cbf5138570c7","target":"record","created_at":"2026-05-18T02:04:36Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3ddceb0c1e5aceca34e268c064524f990fe83d0d8f59d4534871072d4947210c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2010-12-01T13:14:01Z","title_canon_sha256":"6e08b0d729a1dba12a450d4e948cc7082eb025793d0e70c0a39df41e1acbefc7"},"schema_version":"1.0","source":{"id":"1012.0185","kind":"arxiv","version":2}},"canonical_sha256":"65e1d4eb3b92345ff283050e8d179c4b6e0d5cb5a0b53297486f2ab2232d04f3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"65e1d4eb3b92345ff283050e8d179c4b6e0d5cb5a0b53297486f2ab2232d04f3","first_computed_at":"2026-05-18T02:04:36.655476Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:04:36.655476Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"H7f0Fu7aLFXcUIWeL/41/RrRXAAciz9XQ2j3KCdWjisWOaU2lF7rXgmxCknKujpmSCciRG3+HVl8wupOWcF9BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:04:36.656169Z","signed_message":"canonical_sha256_bytes"},"source_id":"1012.0185","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b5957414c8597f7fe993eee3d1f2bc2eca92103e1d65b2f842f6cbf5138570c7","sha256:2ae9a22ec6bbaafd4c7f70ae34d87140a49b1ba15bf4f1d1c90df390741723d6"],"state_sha256":"03db58fd2fbee239ddaf6534678bbc7f34db06f2cdaf3f45abdf953a5e86e908"}
