Radio-only and Radio-to-far-ultraviolet Spectral Energy Distribution Modeling of 14 ULIRGs: Insights into the Global Properties of Infrared Bright Galaxies

The Astrophysical Journal
We present detailed spectral energy distribution (SED) modeling of 14 local ultraluminous infrared galaxies (ULIRGs) with outstanding photometric data from the literature covering the ultraviolet–infrared (FIR) and radio bands (∼50 MHz to ∼30 GHz).

B3 0003+387: AGN Marked Large-Scale Structure at z=1.47?

, 2000
We present evidence for a significant overdensity of red galaxies, as much as a factor of 14 over comparable field samples, in the field of the z=1.47 radio galaxy B3 0003+387. The colors and luminosities of the brightest red galaxies are consistent with

What Triggers Radio Galaxies?

, 2006
We are investigating possible triggering scenarios which may give rise to powerful jetted active galaxies such as classical double radio galaxies. Important clues come from studying those objects which have most recently been triggered. The newly discovered 'Youth-Redshift Degeneracy' for classical double radio galaxies means that the highest redshift ...

Radio Continuum Halos of Seven Nearby Large Galaxies Using uGMRT

The Astrophysical Journal
We present the results of deep radio observations of seven nearby large galaxies observed using the upgraded Giant Metrewave Radio Telescope (uGMRT) 0.3–0.5 GHz receivers with an angular resolution of ∼10″.

To the problem of the secondary CMB anisotropy separation

EPJ Web of Conferences, 2016
We study contribution to the secondary anisotropy maps of cosmic microwave background (CMB) radiation which difficult to account for faint sources. Two effects are investigated.

Quenching through Tidal Gas Removal: Molecular Gas and Star Formation in Tidal Tails of z ∼ 0.7 Post-starburst Galaxies

The Astrophysical Journal
The active suppression of star formation in galaxies is critical for preventing the growth of overly massive systems and explaining the formation of present-day elliptical galaxies.

Mid-infrared Ensemble Variability of Broad-line and Narrow-line Seyfert 1 Galaxies

The Astrophysical Journal
We utilized multiepoch archival data from the Wide-field Infrared Survey Explorer to compare the variability at 3.4 μ m (W1 band) and 4.6 μ m (W2 band) of broad-line Seyfert 1 (BLSy1) galaxies and narrow-line Seyfert 1 (NLSy1) galaxies by employing the ...
