NIRDust: Probing Hot Dust Emission Around Type 2 AGN Using K-band Spectra
Gaia Gaspar, Martín Chalela, Juan Cabral +3
Hot dust in the proximity of AGNs strongly emits in the Near Infrared producing a red excess that, in type 2 sources, can be modeled to measure its temperature. In the era of high…
Compact Groups analysis using weak gravitational lensing II: CFHT Stripe 82 data
Martín Chalela, Elizabeth J. Gonzalez, Martín Makler +4
In this work we present a lensing study of Compact Groups (CGs) using data obtained from the high quality Canada-France-Hawaii Telescope Stripe 82 Survey. Using stacking techniques…
Compact Groups analysis using weak gravitational lensing
Martín Chalela, Elizabeth Johana Gonzalez, Diego Garcia Lambas +1
We present a weak lensing analysis of a sample of SDSS Compact Groups (CGs). Using the measured radial density contrast profile, we derive the average masses under the assumption o…
