Statistics of the excursion sets in models with local primordial non-Gaussianity (2010)
Rossi, Graziano, Chingangbam, Pravabati, Park, Changbom
We use the statistics of regions above or below a temperature threshold (excursion sets) to study the cosmic microwave background (CMB) anisotropy in models with primordial non-Gaussianity of the...

In addition to the maximum likelihood approach, there are two other methods which are commonly used to reconstruct the true redshift distribution from photometric redshift datasets: one uses a...
Non-Gaussian Distribution and Clustering of Hot and Cold Pixels in the WMAP Five-Year Sky (2009)
Rossi, Graziano, Sheth, Ravi K., Park, Changbom, Hernandez-Monteagudo, Carlos
We present measurements of the clustering of hot and cold patches in the microwave background sky as measured from the Wilkinson Microwave Anisotropy Probe (WMAP) five-year data. These measurements...
Rossi, Graziano, Sheth, Ravi K., Park, Changbom
Noisy distance estimates associated with photometric rather than spectroscopic redshifts lead to a mis-estimate of the luminosities, and produce a correlated mis-estimate of the sizes. We consider a...

Effect of Distance Errors: Applications to SDSS Early-Type Galaxies (2008)
Rossi, Graziano, Sheth, Ravi K.
Noisy distance estimates associated with photometric rather than spectroscopic redshifts lead to a mis-estimate of the luminosities, and produce a correlated mis-estimate of the sizes. We consider a...
Gaussianity, non-Gaussianity, and photometric redshift surveys (2008)
Many physical properties of galaxies correlate with one another, and these correlations are often used to constrain galaxy formation models. However, the transformation from observable to physical...
Genome Size and GC Content Evolution of Festuca: Ancestral Expansion and Subsequent Reduction (2008)
Smarda, Petr, Bures, Petr, Horová, Lucie, Foggi, Bruno, Rossi, Graziano
Background and Aims Plant evolution is well known to be frequently associated with remarkable changes in genome size and composition; however, the knowledge of long-term evolutionary dynamics of...
Unbiased estimates of galaxy scaling relations from photometric redshift surveys (2007)
Rossi, Graziano, Sheth, Ravi K.
Many physical properties of galaxies correlate with one another, and these correlations are often used to constrain galaxy formation models. Such correlations include the color-magnitude relation,...
Limited Genome Size Variation in Sesleria albicans (2000)
Lysák, Martin A., Rostková, Alexandra, Dixon, Jean M., Rossi, Graziano, Dolezel, Jaroslav
The extent and significance of intraspecific genome size variation in plants continues to be a matter of discussion: in some species considerable variation has been described, while no variation has...
