Rawat, Abhishek, Wadadekar, Yogesh, De Mello, Duilia
We show a comparison of the rest-frame UV morphologies of a sample of 162 intermediate redshift (median redshift 1.02) galaxies with their rest-frame optical morphologies. We select our sample from...
Near Ultraviolet sources in the Great Observatories Origins Deep Survey Fields (2006)
De Mello, Duilia, Dahlen, T., Gardner, J. P., Grogin, N. A.
We present an Ultraviolet (UV) selected sample of 268 objects in the two fields of the Great Observatories Origins Deep Survey (GOODS). We used the parallel observations taken with WFPC2 in the...
Faint U-Band Dropouts in the WFPC2 Parallels of the Hubble Ultra Deep Field (2006)
Wadadekar, Yogesh, Casertano, Stefano, De Mello, Duilia
We combine data from the extremely deep Hubble Space Telescope $U$ (F300W) image obtained using WFPC2 as part of the parallel observations of the Hubble Ultra Deep Field campaign, with $BVi$ images...
Chandar, Rupali, Leitherer, Claus, Tremonti, Christy A., Calzetti, Daniela, Aloisi, Alessandra, Meurer, Gerhardt R., ...
We investigate the nature of the diffuse intra-cluster ultraviolet light seen in twelve local starburst galaxies, using long-slit ultraviolet spectroscopy obtained with the Space Telescope Imaging...
Metal enrichment in near-IR luminous galaxies at z~2: signatures of proto-ellipticals? (2004)
De Mello, Duilia, Daddi, E., Renzini, A., Cimatti, A., Alighieri, S. Di Serego, Pozzetti, L., ...
We present the analysis of the coadded rest-frame UV spectrum (1200
Structure and Evolution of Starburst and Normal Galaxies (2003)
Mobasher, Bahram, Jogee, Shardha, Dahlen, Tomas, De Mello, Duilia, Conselice, Christopher, Grogin, Norman, ...
We study the rest-frame morphology and structural properties of optically selected starburst galaxies at redshift z < 1, using multi-waveband (BViz) high resolution images taken by the Advanced...
Observing the Formation of the Hubble Sequence in the Great Observatories Origins Deep Survey (2003)
Conselice, Christopher J., Grogin, Norman A., Jogee, Shardha, Lucas, Ray A., Dahlen, Tomas, De Mello, Duilia, ...
Understanding the physical formation of the Hubble sequence remains one of the most important unsolved astrophysical problems. Searches for proto-disks and proto-ellipticals can now be effectively...

The Hubble Deep Field South Flanking Fields (2002)
Lucas, Ray A., Baum, Stefi A., Brown, Thomas M., Casertano, Stefano, Conselice, Chris, De Mello, Duilia, ...
As part of the Hubble Deep Field South program, a set of shorter 2-orbit observations were obtained of the area adjacent to the deep fields. The WFPC2 flanking fields cover a contiguous solid angle...
The Nature of Submm-Detected Galaxies (2002)
De Mello, Duilia, Wiklind, T., Leitherer, C., Pontoppidan, K.
We present high resolution VLT spectra of 2 submm-detected galaxies. Diagnostic stellar absorption lines (Starburst99) are used to analyse their stellar population. SMM J14011+0252 (z=2.565) shows...
WFPC2 Observations of the Hubble Deep Field-South (2000)
Casertano, Stefano, De Mello, Duilia, Dickinson, Mark, Ferguson, Henry C., Fruchter, Andrew S., Gonzalez-Lopezlira, Rosa A., ...
The Hubble Deep Field-South observations targeted a high-galactic-latitude field near QSO J2233-606. We present WFPC2 observations of the field in four wide bandpasses centered at roughly 300, 450,...
Searching for WR stars in I Zw 18 -- The origin of HeII emission (1998)
De Mello, Duilia, Schaerer, Daniel, Heldmann, Jennifer, Leitherer, Claus
I Zw 18 is the most metal poor star-forming galaxy known and is an ideal laboratory to probe stellar evolution theory at low metallicities. Using archival HST WFPC2 imaging and FOS spectroscopy we...
Massive star populations in I Zw 18: A probe of stellar evolution in the early universe (1998)
Schaerer, Daniel, De Mello, Duilia, Leitherer, Claus, Heldmann, Jennifer
We present a study of the gaseous and stellar emission in I Zw18, the most metal-poor star-forming galaxy known. Archival HST WFPC2 and FOS data have been used to analyze the spatial distribution of...
