We present GBT-EDGE, a new CO(1-0) survey using the Green Bank Telescope to map 62 nearby (10-140 Mpc) galaxies spanning the star-forming main sequence (SFMS), green valley, and re…
The GMRT archive atomic gas survey -- IV. Consistency of the dark matter halo perturbation parameter from morphological and kinematic lopsidedness of galaxies
Prerana Biswas, Narendra Nath Patra, Veselina Kalinova
The lopsidedness of galaxies is a commonly observed phenomenon, and through different studies, it has been observed that nearly 30% of galaxies show this phenomenon. In this work,…
Scaling Relations across Galaxy Classification Schemes: I. Star Formation Rate-Stellar Mass Plane of CALIFA Nearby Galaxies
Veselina Kalinova, Keiichi Kodaira, Dario Colombo
To gain deeper insights into galaxy evolution and the mechanisms driving transitions between different galaxy morphologies, we analyse the connection between star formation rate an…
The GMRT archive atomic gas survey -- III. Comparative Study of Dark Matter Halos in Nearby Galaxies
Sougata Sarkar, Prerana Biswas, Veselina Kalinova +3
The distribution of dark matter in the inner regions of galaxies poses a key challenge for small-scale ΛCDM cosmology. While cold dark matter simulations predict cuspy inner densit…
The vertical structure of the stellar disk in NGC 551
Harshal Raut, Narendra Nath Patra, Prerana Biswas +6
We self-consistently determine the 3D density distribution of NGC 551's stellar disk and study observational signatures of two-component stellar disks. Assuming baryonic disks are…
The EDGE-CALIFA survey: The effect of active galactic nucleus feedback on the integrated properties of galaxies at different stages of their evolution
Z. Bazzi, D. Colombo, F. Bigiel +5
Galaxy quenching, the intricate process through which galaxies transition from active star-forming states to retired ones, remains a complex phenomenon that requires further invest…
The EDGE-CALIFA survey: Star formation relationships for galaxies at different stages of their evolution
D. Colombo, V. Kalinova, Z. Bazzi +13
Galaxy evolution is largely driven by star formation activity or by the cessation of it, also called star formation quenching. In this paper, we present star formation scaling rela…
The EDGE-CALIFA Survey: An integral field unit-based integrated molecular gas database for galaxy evolution studies in the Local Universe
D. Colombo, V. Kalinova, Z. Bazzi +14
Studying galaxy evolution requires knowledge not only of the stellar properties, but also of the interstellar medium (in particular the molecular phase) out of which stars form, us…
The EDGE-CALIFA Survey: An Extragalactic Database for Galaxy Evolution Studies
Tony Wong, Yixian Cao, Yufeng Luo +22
The EDGE-CALIFA survey provides spatially resolved optical integral field unit (IFU) and CO spectroscopy for 125 galaxies selected from the CALIFA Data Release 3 sample. The Extrag…
The EDGE-CALIFA survey: Molecular Gas and Star Formation Activity Across the Green Valley
Vicente Villanueva, Alberto D. Bolatto, Stuart N. Vogel +11
We present a CO(=2-1) survey of 60 local galaxies using data from the Atacama Large Millimeter/submillimeter Compact Array as part of the Extragalactic Database for Galax…
The GMRT archive atomic gas survey -- II. Mass modelling and dark matter halo properties across late-type spirals
Prerana Biswas, Veselina Kalinova, Nirupam Roy +2
Studying the kinematics and mass modelling of galaxies from HI 21 cm data provides valuable insights into the properties of both the baryonic components and the dark matter halo in…
The EDGE-CALIFA survey: The role of spiral arms and bars in driving central molecular gas concentrations
Si-Yue Yu, Veselina Kalinova, Dario Colombo +9
Shocks and torques produced by non-axisymmetric structures such as spiral arms and bars may transport gas to galaxy central regions. We test this hypothesis by studying the depende…
Investigating the link between inner gravitational potential and star-formation quenching in CALIFA galaxies
V. Kalinova, D. Colombo, S. F. Sánchez +9
It has been suggested that the gravitational potential can have a significant role in suppressing the star formation in the nearby galaxies. To establish observational constrains o…
The EDGE-CALIFA survey: The resolved star formation efficiency and local physical conditions

The EDGE-CALIFA Survey: Central molecular gas depletion in AGN host galaxies -- a smoking gun for quenching?
Sara L. Ellison, Tony Wong, Sebastian F. Sanchez +8
Feedback from an active galactic nucleus (AGN) is often implicated as a mechanism that leads to the quenching of galactic star formation. However, AGN-driven quenching is challengi…
