<p>Stellar populations relations on the Fundamental Plane</p>
</header>
<!--<span class="image fit"><img src="images/banner.jpg" alt="" /></span>-->
<p>Early-type galaxies (ETGs) are characterised by regular shapes and smooth stellar profiles.
They typically harbor old stellar populations and have no current star formation. In
the parameter space defined by luminosity L, velocity dispersion σ and half-light
radius R, ETGs occupy a narrow locus, the Fundamental Plane (FP). The existence of this
plane is explained by the dynamically relaxed nature of ETGs and by the virial theorem.
However, the FP is 'tilted' with respect to the virial plane, an effect that has been
shown to derive from a systematic variation of the mass-to-light ratio \(\Upsilon\) along the
virial plane (Cappellari et al. 2006, 2013a).</p>
<img src="images/research_fp/fp_age.png" alt="" align='left' style="padding: 7px 15px; float; left;" width="450"/>
<p>
In <a href="http://adsabs.harvard.edu/abs/2018ApJ...856...64B" target="_blank">Barone et al. (2018)</a>, we have shown that the stellar population properties of ETGs are linked to the structural parameters of galaxies. With the large sample size of SAMI, we aim at quantifying the contribution of the stellar population trends to the tilt and scatter of the FP. In <a href="https://ui.adsabs.harvard.edu/abs/2021MNRAS.504.5098D" target="_blank">D'Eugenio et al. (2021),</a>
we find that stellar population trends contribute approximatel 50-75% of the FP
<i>intrinsic</i> scatter. This is important not only for galaxy evolution studies,
but also for cosmology: the FP intrinsic scatter will be the hard limit to
the precision of FP-inferred distances, hence to the precision of near-field cosmology
studies.
In particular, the intrinsic scatter of the FP has been a limiting factor in its
application as a distance indicator <a href="http://adsabs.harvard.edu/abs/2012MNRAS.427..245M" target="_blank">(Magoulas et al. 2012)</a>. Stellar population age has been
shown to be linked to the scatter (see figure), so that taking this parameter into account could
reduce the scatter thereby improving the precision of the FP as a tool for Cosmology.
Past attempts in this sense have been frustrated by noisy age measurements. With SAMI,
we can measure precise ages for a large sample of ETGs, therefore it is worthwhile to
check whether we can effectively reduce the measurement uncertainties on FP-derived
distances.
