Dear colleagues,
I have just seen the post here which is related to our work. In
Astro-ph/0507482 we did a thorough investigation of the dark energy perturbation in the case of the equation of state crossing -1 based on quintom dark energy model proposed in
Astro-ph/0404224.
Further, in
Astro-ph/0511625 we did a MCMC analysis to determine the cosmological parameters using the method in
Astro-ph/0507482. Most of the contours, especially for the dark energy parameters, get enlarged.
I regret many aspects in the literature regarding the fact that the credit of getting across -1 scenario has not been properly given and shall I list the relevant papers below from our group as follows.
Cheers,
Gong-Bo Zhao
